Answer:
a)
b)
Explanation:
Given that:
diameter d = 12 in
thickness t = 0.25 in
the radius = d/2 = 12 / 2 = 6 in
r/t = 6/0.25 = 24
24 > 10
Using the thin wall cylinder formula;
The valve A is opened and the flowing water has a pressure P of 200 psi.
So;
b)The valve A is closed and the water pressure P is 250 psi.
where P = 250 psi
The free flow body diagram showing the state of stress on a volume element located on the wall at point B is attached in the diagram below
Answer:
b. spark plugs
Explanation:
Diesel engines are characterized in that the mechanism that activates the explosion of fuel is high pressures, so when the piston reaches the top of the cylinder, the pressure of the air-diessel mixture is so high that it causes the explosion, this It is what generates the power in a diesel engine.
Answer:
discharge = 0.310976 m³/s
Explanation:
given data
rectangular channel wide = 2.9 m
length of weir L = 1.9 m
water level H = 0.2 m
solution
we get here discharge that is express as
discharge = ............................1
we consider here Coefficient of discharge Cd = 0.62
put here value we get
discharge =
discharge = 0.310976 m³/s
