steam enters a steady-flow turbine with a mass flow rate of 13 kg/s at 6008c, 8 mpa, and a negligible velocity. the steam expands in the turbine to a saturated vapor at 300 kpa where 10 percent of the steam is removed for some other use. the remainder of the steam continues to expand to the turbine exit where the pressure is 10 kpa and quality is 85 percent. if the turbine is adiabatic, determine the rate of work done by the steam during this process.

Answers

Answer 1

The problem describes a steady-flow turbine where steam enters at a high temperature and pressure and expands to a lower pressure, producing work. The steam undergoes two stages of expansion,

with a portion of the steam removed at an intermediate pressure for some other use. To solve the problem, one needs to apply the first law of thermodynamics to the control volume enclosing the turbine. Since the turbine is adiabatic, there is no heat transfer, and the work done by the steam is equal to the decrease in its enthalpy. The enthalpy change is evaluated using steam tables or thermodynamic software for the given initial and final states of the steam. After solving for the enthalpy change and accounting for the portion of steam removed, one can calculate the rate of work done by the steam during the process.

Consider an LRC series circuit. The impedance of the circuit increases if XC increases. When is this statement true?

Answers

Answer:

  at frequencies below resonance

Explanation:

Below resonance, circuit impedance decreases as XC decreases with increasing frequency. Above resonance, circuit impedance increases as XL increases with frequency. Hence increasing circuit impedance will only accompany increasing XC below resonance (as frequency decreases).

____

Below resonance, |XL| < |XC|, so XC dominates series impedance. Above resonance, the reverse is true.

Answers

The four processes that make up the Carnot cycle are: 1) Isothermal Expansion, 2) Adiabatic Expansion, 3) Isothermal Compression, and 4) Adiabatic Compression.


The Carnot cycle is an idealized thermodynamic cycle that demonstrates the theoretical maximum efficiency for a heat engine. The cycle consists of four reversible processes:

1. Isothermal Expansion: The working substance, usually a gas, is allowed to expand at a constant temperature while absorbing heat from a high-temperature reservoir.

2. Adiabatic Expansion: The gas continues to expand, but without any heat exchange with the surroundings. During this process, the temperature of the gas decreases.

3. Isothermal Compression: The gas is compressed at a constant temperature while releasing heat to a low-temperature reservoir.

4. Adiabatic Compression: The gas is further compressed without any heat exchange with the surroundings. During this process, the temperature of the gas increases.

The Carnot cycle serves as an ideal benchmark for real heat engines, as it represents the highest possible efficiency that any heat engine can achieve.

If the cord speed at point P is v-2.0 mys, determine the velocities of points A and B. No slipping occurs. Answers: Ve- mis

Answers

GivenDataRadius of the spoked wheel, r = 705 mmCord speed at point P, v = 2.0 m/sVelocity of point E = VeWe know that linear velocity (v) = angular velocity (ω) × radius (r)We can find the angular velocity using the formula:ω = v / rω = 2 / 0.705= 2.84 rad/s

We know that the velocity of point A is perpendicular to the incline and the velocity of point E is parallel to the incline.As no slipping occurs, the velocity of point B is zero.The velocity of point E is given byVe = ω × r = 2.84 × 0.705 = 2.00 m/sLet VA be the velocity of point A. Then we can write:VA / Ve = AB / AEBut AB = 2r and AE = r + hSo we haveVA / 2 = AB / (r + h)VA / 2 = 2r / (r + h)VA = 4r / (r + h)Substitute the values to obtainVA = 4 × 705 / (705 + 300) = 2.22 m/sTherefore, the velocities of points A and B are VA = 2.22 m/s and VB = 0 m/s respectively.Note that the solution has a word count of 159 words.

#SPJ11

According to the information, the velocity of point A is v = 1.0 m/s and the velocity of point B is v = 2.0 m/s.

How to calculate the velocity of point A and point B?

Fist we have to consider that since no slipping occurs, the linear velocity of any point on the wheel must be equal to the tangential velocity of the cord. At point P, the cord speed is given as v = 2.0 m/s.

Now, to determine the velocities of points A and B, we need to consider the relationship between linear velocity, angular velocity, and radius. The linear velocity of a point on the wheel is equal to the product of the angular velocity and the radius of the wheel.

Additionally, the radius of the wheel is given as r = 705 mm, which is equivalent to 0.705 m, we can calculate the angular velocity (ω) of the wheel by dividing the linear velocity of point P (v) by the radius (r).

ω = v / r = 2.0 m/s / 0.705 m ≈ 2.836 rad/s

Now, we can calculate the velocities of points A and B using the angular velocity and their respective radii.

Velocity of point A:

v_A = ω * r_A = 2.836 rad/s * r_A

Velocity of point B:

v_B = ω * r_B = 2.836 rad/s * r_B

Since the radius of point A (r_A) is 0.705 m, the velocity of point A is:

v_A = 2.836 rad/s * 0.705 m = 2.0 m/s

Since the radius of point B (r_B) is twice the radius of point A, i.e., 2 * 0.705 m = 1.41 m, the velocity of point B is:

v_B = 2.836 rad/s * 1.41 m = 4.0 m/s

According to the above, the velocity of point A is v_A = 2.0 m/s and the velocity of point B is v_B = 4.0 m/s.

Question:

Calculate the equivalent capacitance of the three series capacitors in Figure 12-1

a) 0.01 μF

b) 0.58 μF

c) 0.060 μF

d) 0.8 μF

Answer:

The equivalent capacitance of the three series capacitors in Figure 12-1 is 0.060 μF

Therefore, the correct option is (c)

Explanation:

Please refer to the attached Figure 12-1 where three capacitors are connected in series.

We are asked to find out the equivalent capacitance of this circuit.

Recall that the equivalent capacitance in series is given by

\($ \frac{1}{C_{eq}} = \frac{1}{C_{1}} + \frac{1}{C_{2}} + \frac{1}{C_{3}} $\)

Where C₁, C₂, and C₃ are the individual capacitance connected in series.

C₁ = 0.1 μF

C₂ = 0.22 μF

C₃ = 0.47 μF

So the equivalent capacitance is

\($ \frac{1}{C_{eq}} = \frac{1}{0.1} + \frac{1}{0.22} + \frac{1}{0.47} $\)

\($ \frac{1}{C_{eq}} = \frac{8620}{517} $\)

\($ C_{eq} = \frac{517}{8620} $\)

\($ C_{eq} = 0.0599 $\)

Rounding off yields

\($ C_{eq} = 0.060 \: \mu F $\)

The equivalent capacitance of the three series capacitors in Figure 12-1 is 0.060 μF

Therefore, the correct option is (c)

a. will a detect the collision is dprop > l/r? why or why not?

Answers

Answer:

Explanation:

A. No, "A" will not detect the collision** based on the condition **dprop > l/r.

The condition dprop > l/r refers to the time taken for a signal to propagate across the link (dprop) being greater than the time it takes to transmit a packet (l) divided by the rate of transmission (r). This condition is used to determine if two packets will collide on a shared transmission medium.

However, "A" alone cannot detect collisions based on this condition. The reason is that "A" does not have access to the necessary information such as the propagation delay, packet length, or transmission rate.

Collision detection typically requires additional mechanisms such as Carrier Sense Multiple Access with Collision Detection (CSMA/CD) in Ethernet networks. CSMA/CD allows devices to listen to the transmission medium and detect if there is already ongoing transmission before sending their own packets. If a collision is detected, devices implement collision resolution procedures to handle the collision.

Therefore, "A" alone cannot detect collisions based on the condition dprop > l/r.

The analog telephone signal must be sampled at a minimum of 8 kHz to be converted to digital using PCM.

In order to represent sampled analogue signals digitally, one technique is pulse-code modulation (PCM). It serves as the industry standard for digital audio in applications such as digital telephony, compact discs, and computers. In a PCM stream, overall amplitude of the analogue signal is quantized to a nearest value inside a range of digital steps for each regular, uniformly spaced sample.

A particular variant of PCM called linear pulse-code modulation (LPCM) has linearly uniform quantization levels. In contrast, PCM encodings (such as those using the A-law or -law algorithms) have quantization levels that are dependent on amplitude. PCM is a more broad term, but it's frequently used to refer to data that has been encoded using LPCM.

If the temperature of a gas is raised from 100°C to 200°C, the average kinetic energy of the molecules will double. This is because the temperature increase is a 100% increase, and the average kinetic energy of the molecules will also increase by 100%.

Taking care of" is a very human term in the sense of care giving, but so is "parents", because animals do not retain family structures in the form humans do. The vast majority of animals do not recognize family members. Among predators, an aging parent, such as the male lion in a pride, would continue to be taken care of by the females just as they always were, until a stronger outside male ousted it. An aging silverback in a group of gorillas would eventually be challenged and overthrown by one of his sons. When the elder became too infirm to care for itself, it would go off by itself to die. The only animal species that modify their behavior due to familial bonds to accommodate the needs of an aging member of the family are Cetaceans (whales) and Pachyderms (elephants). Whales have been seen to bouy up an ailing member of the pod (an extended family) to keep it from sinking. Elephants have the closest family ties of all animals, the eldest surviving female, the Matriarch of a herd, might be the great, great, great grandmother to the youngest and the others in varying relationships, are mothers, grandmothers, children, sisters, aunts and cousins, the older always taking care of and sheltering the younger. They also shelter and accommodate the older. If one member is sick or too old to keep up, the rest of the herd will slow down to allow the lagging one to keep up. This "caring" behavior has its limitations. The herd will not endanger itself to stay with an ailing member who will never be able to keep up. However, when the Matriarch herself is dying of old age, and the herd is in an area where food and water are abundant, the rest of the herd will stay with her, comfort her with their trunks, caressing her, talking to her, vocalizing over her, never leaving her side. While some are foraging, there will always be a group around her comforting her and expressing their love. (Scientists used to dismiss that term as inapplicable to animals, but the evidence is overwhelming that higher animal species have the same emotions humans do.) The herd will remain with her body, mourning, for several days, and years later will still return to fondle her bones with their trunks. Eventually one of the Matriarch's daughters will be chosen as the one to follow, or even two in which case the herd would divide into two new herds, the daughters and their offspring of each new Matriarch following their own family line.
