(a) What is the absolute pressure at point at point 1 if the valve is closed, assuming that the top surface of the water at point 2 is at atmospheric pressure.
(b) What is the absolute pressure at point 1 when the valve is opened and the water is flowing? Assume that the water speed at point 2 is negligible.
(c) Assuming the effective cross-sectional area of the valve opening is 2.00*10^-2 m^2. Find the volume of the flow at point 1.
The water tower in the drawing is drained by a pipe that extends to be the ground. The flow is nonviscous.?
where's the drawing?
