A hydraulic reservoir pressurised to 12,5 kPa contains a fluid with a density of 960 kg/m³. The reservoir feeds a hydraulic pump with a flow rate of 10 l/s through a filter with a shock loss constant (k) of 4.
After the pump, there are two bends, each with a shock loss constant (k) of 0,85 and a selector valve with a length to diameter ratio of 60. The actuator requires a pressure of 4,25 MPa to operate. The actuator is located 6 m lower than the fluid level in the reservoir. A 30 mm diameter pipe of 15 m connects the components. The pipe has a friction coefficient of 0,015. Calculate: 6.2.1 The total length to diameter ratio of the system (ignore entrance loss to the pipe.) 6.2.2 The total head loss throughout the system

The probability that the patient's specimen will be flagged as "unusually high" if the reported value is the mean of three independent assays is approximately 0.0668 or 6.68%.

To discover the likelihood that a patient's specimen will be flagged as "unusually high" given the detailed value as the mean of three free tests, we got to calculate the likelihood of getting a mean ALT concentration of 40 or more.

The cruel of three free measures takes after a ordinary dispersion with the same cruel as the person tests but a diminished standard deviation. Since the standard deviation of each person test is 4 U/l, the standard deviation of the cruel of three measures can be calculated as takes after:

Standard deviation of the cruel = Standard deviation of person measures / sqrt(Number of measures)

= 4 U/l / sqrt(3)

Presently, we will calculate the z-score for the detailed esteem of 40 U/l utilizing the patient's genuine ALT concentration of 35 U/l and the standard deviation of the cruel of three measures:

z-score = (detailed esteem - genuine esteem) / standard deviation of the cruel

= (40 - 35) / (4 / sqrt(3))

Calculating the z-score:

z-score = 5 / (4 / sqrt(3))

= 5 * sqrt(3) / 4

Following, we have to be find the likelihood of getting a z-score greater than or rise to to the calculated z-score. This could be done by looking up the comparing aggregate likelihood within the standard typical dissemination table or by employing a calculator or computer program.

Let's accept we utilize a standard typical conveyance table. Looking up the esteem of z-score = 5 * sqrt(3) / 4 within the table, we discover that it is around 0.9332.

Be that as it may, we require the likelihood of getting a z-score more noteworthy than or break even with to the calculated z-score, so we subtract this esteem from 1:

Likelihood = 1 - 0.9332

= 0.0668

Hence, the likelihood that the patient's example will be hailed as "curiously tall" in the event that the detailed esteem is the cruel of three free tests is around 0.0668 or 6.68%.

Response:

The composition of gas in the product stream are;

The amount of oxygen used = 30% exceeding the theoretical amount

Number of moles of hydrochloric acid = 4 kmol/h

Percentage conversion = 80%

Required:

The composition of the gas in the product feed.

Solution;

The given reaction is; 4HCl + O₂ \(\longrightarrow\) 2Cl₂ + 2H₂O

\(Percentage \ conversion = \mathbf{ \dfrac{Moles \ of \ limiting \ reactant \ reacted}{Moles \ of \ limiting \ reactant \ supplied \ in \ the \, feed}}\)

Which gives;

\(80 \% = \mathbf{ \dfrac{Moles \ of \ limiting \ reactant \ reacted}{4 \, kmol/h}}\)

Moles of limiting reactant reacted = 4 kmol/h × 0.80 = 3.6 kmol/h

Which gives;

Number of moles of HCl in the stream = 4 kmol/h - 3.6 kmol/h = 0.4 kmol/h

Number of moles of Cl₂ produced = 2 kmol/h × 0.8 = 1.6 kmol/h

Similarly;

Number of moles of H₂O produced = 2 kmol/h × 0.8 = 1.6 kmol/h

Number of moles of O₂ in the product stream = 30% × 1 kmol/h + 20% × 1 kmol/h = 0.5 kmol/h

A 60Hz, 0.5-HP single-phase motor in a washing machine (120V RMS) has an efficiency of 78% at full load (rated output power) and a power factor of 0.72 lagging.

To find the line current, first determine the real power (P) using the formula P = HP × 746, where HP is 0.5. This gives P = 373W. Since efficiency is 78%, the input power (Pin) is P/0.78 = 478.21W. Now, use the power factor (0.72) to find the apparent power (S) by dividing Pin by the power factor: S = 478.21/0.72 = 664.18 VA. To find the line current (I), divide the apparent power (S) by the voltage (120V): I = 664.18/120 = 5.53 A.
The reactive power (Q) can be found using the formula Q = S × sin(arccos(0.72)), resulting in Q = 664.18 × sin(arccos(0.72)) = 536.65 VAR. In summary, the line current is 5.53 A, the reactive power is 536.65 VAR, and the apparent power is 664.18 VA.

Answer:

  9.29 N . . . . weight of 0.948 kg sphere

Explanation:

The sum of torques on the link BOA is zero, so we have ...

  (right force at A)(OA) = (up force at B)(OB·sin(135°))

Solving for the force at B, we have ...

  up force at B = (10.53 N)(253 mm)/((553 mm)/√2) ≈ 6.81301 N

This force is due to the difference between the buoyant force on the float sphere and the weight of the float sphere. Dividing by the acceleration due to gravity, it translates to the difference in mass between the water displaced and the mass of the sphere.

  ∆mass = (6.81301 N)/(9.8 m/s^2) = 0.695205 kg

__

The center of the sphere of diameter 0.1553 m is below the waterline by ...

  (553 mm)cos(45°) -(353 mm) = 38.0300 mm

The volume of the spherical cap of radius 155.3/2 = 77.65 mm and height 77.65+38.0300 = 115.680 mm can be found from the formula ...

  V = (π/3)h^3(3r -h) = (π/3)(115.680^2)(3·77.65 -115.68) mm^3 ≈ 1.64336 L

So the mass of water contributing to the buoyant force is 1.64336 kg. For the net upward force to correspond to a mass of 0.695305 kg, the mass of the float sphere must be ...

  1.64336 kg -0.695205 kg ≈ 0.948 kg

The weight of the float sphere is then (9.8 m/s^2)·(0.948 kg) = 9.29 N

The weight of the 0.948 kg float sphere is about 9.29 N.

The temperature of the filament within the lightbulb can be altered by a factor of 10²⁵ by applying the blackbody radiation formula.

To tackle this issue, we need to understand black body radiation. A black body object's energy emission is inversely proportional to its area and the temperature to the fourth power. It can be calculated using the formula P = A e. T4, where is Stefan Boltzmann's constant (5.67x10⁸W/m/2K4), P is power, A is surface area, e is emissivity, and A is surface area.

We can deduct from the previous query that P1 = 10 watts and P2 = 100 watts.

The temperature ratio is T14/T24 = P1/P2 according to the black body radiation formula, which means that T2 = (T1*10⁴)/4

T2=T1 x 100²⁵.

As a result, the filament's internal temperature is altered by a factor of 10²⁵.

Yes, a pulsed current can have a zero net charge. This is because a pulsed current is a flow of electric charges that alternate in direction, creating a series of electrical pulses.

The net charge of a pulsed current is determined by the difference between the number of positive and negative charges flowing through the circuit. If the number of positive charges is equal to the number of negative charges, the net charge is zero.
Yes, a pulsed current can have a zero net charge. In a pulsed current, the flow of electric charge alternates between intervals of movement and no movement. If the positive and negative charges flowing in the current cancel each other out over time, the net charge will be zero. This means that the total amount of positive charge equals the total amount of negative charge, resulting in no overall charge being transferred.

Answer:

True.

Explanation:

The compressibility of a fluid can be defined as a measure of the change in volume (density) with respect to the amount of pressure applied to the fluid. Thus, as the pressure of a compressible fluid increases, both its viscosity and density increases.

Some examples of compressible fluids are vapors, gases, air etc.

Additionally, the compressibility of fluids plays a significant role in the field of science such as in aerodynamics, fluid mechanics, thermodynamics etc.

Viscosity can be defined as a quantity expressing the magnitude of internal friction that restricts the ease of flow between parallel layers at some distance apart having unit speed relative to each other.

These properties of fluids, including viscosity and compressibility are usually being studied by engineers such as civil engineers, in order to test the efficiency of systems under given conditions.

A material's susceptibility to drawing is how the mechanical feature of ductility is most frequently defined (e.g. into wire). The degree to which a material can withstand plastic deformation under tensile stress before failing is referred to as ductility in the field of materials research.

In engineering and manufacturing, ductility is a crucial factor. It specifies a material's ability to withstand mechanical overload and its appropriateness for specific manufacturing processes, including cold working. Gold and copper are two examples of metals that are typically referred to as ductile.

However, not all metals are brittle, as some, like cast iron, are capable of ductile failure. Polymers can commonly be thought of as ductile materials since they frequently permit plastic deformation.
