A water tank filled with solar-heated water at 40°C is to be used for showers in a field using gravity-driven flow.


The system includes 35 m of 1.5-cm-diameter galvanized iron piping with four miter bends (90°) without vanes and a wide-open globe valve.



If water is to flow at a rate of 1.2 L/s through the shower head, determine how high the water level in the tank must be from the exit level of the shower.



Disregard the losses at the entrance and at the shower head, and neglect the effect of the kinetic energy correction factor. The density and dynamic viscosity of water at 40°C are rho = 992.1 kg/m3 and μ = 0.653 × 10–3 kg/m·s.


The roughness of galvanized iron pipe is ε = 0.00015 m. Ignore the minor losses.The free surface of the tank must be_____ m above the shower exit to ensure water flow at the specified rate.

1) A cylinder has a volume of 20 cubic feet. What is that volume in cubic inches? (1 ft = 12 in) ​

Answers

Before calculating the volume of this cylinder, we must either convert the diameter to feet or the height to inches. I'll do the latter, to avoid getting a very small number.
Recall that there are

Hence, the cylinder has a height of

If an engine-driven hydraulic pump of the correct capacity fails to maintain normal system pressure during the operation of a cowl flap actuating unit, the probable cause is

Answers

Answer:

The correct response will be " restriction in the pump outlet".

Explanation:

As that of the pressure mostly on flow rate, this same desired power or voltage decreases. In plenty of several phrases, if clients place a valve upon that discharge port but instead start limiting the provides an output, the infrastructure consumption either by the engine will significantly decline.

an 8 N weight is placed at one end of a meterstick. a 10N weight is placed at the other end. where should the fulcrum be placed to have the meterstick balanced?

Answers

The fulcrum should be placed 0.44 from the 12 N weight or 0.56 m from the 8 N weight.

Explanation:

Given:

[tex] w_1 [/tex] = 8 N

[tex] w_2 [/tex] = 10 N

Since the meter stick has a length of 1 m, and [tex] d_1 \:+\:d_2\:=\:1\:m [/tex]

Let [tex] d_1 [/tex] = x

Let [tex] d_2 [/tex] = 1 - x

Question:

Where should the fulcrum be placed to have the meterstick balanced?

Equation:

For the system to be balanced, the product of the weight and distance of the objects on opposite sides should be equal. This is is shown by the equation:

[tex]w_1 d_1 = w_2 d_2 [/tex]

where: w - weight

d - distance from the fulcrum

Solution:

Substituting the value of [tex] w_1, \:w_2, \:d_1 \:[/tex] and[tex] \: d_2[/tex] in the formula,

(8 N)(x) = (10 N)(1 m - x)

x(8 N) = (10 N)m - x(10 N)

x(8 N) + x(10 N) = (10 N) m

x(18 N) = 10 N

x = [tex] \frac{(10 \:N)m}{18 \:N}[/tex]

x = 0.56

Solve for [tex] d_1 [/tex]

[tex] d_1 [/tex] = x

[tex] d_1 [/tex] = 0.56 m

Solve for [tex] d_2 [/tex]

[tex] d_2 [/tex] = 1 m - x

[tex] d_2 [/tex] = 1 m - 0.56 m

[tex] d_2 [/tex] = 0.44 m

Final Answer:The fulcrum should be placed 0.44 from the 12 N weight or 0.56 m from the 8 N weight.

A driver complains that his front tires are wearing
excessively at the center of the tread surface. Techni-
cian A says the wear problem is caused by underin-
flation. Technician B says the problem is caused by
excessive camber. Who is right?
(A) A only.
(B) B only.
(C) Both A & B.
(D) Neither A nor B.

Answers

Answer:

The correct option is;

Neither A nor B

Explanation:

The location of the where the thread wears in tire that has too high inflation is at the thread pattern center due to the reduced size of the contact patch with the load of the car resting on the central portion of the tire's contact surface

When the wear occurs at the outer edges of the tire, the load of the car rests on the outer edges as the contact patch increases due to the tire being under-inflated

Camber is the slope provided in road pavement to drain off water from the road

Roads with camber has a raised middle portion and wear due to camber includes outer-edge tread wear, inner-edge tread wear and tire feathering
