Question: Inside of the tank shown in the schematic, water is pressurized …
Inside of the tank shown in the schematic, water is pressurized by a compressed gas on top of the water. The pressure of the gas is measured using a U-tube manometer which has a gage fluid with a SG of 7. At the bottom of the water tank (1.5 m below the surface of the water) a valve with an inside diameter of 2 cm is opened to the atmosphere. If the height difference between the gage fluid surfaces in the U-tube is 7.5 cm, determine a) the velocity of the water leaving the valve and b) the mass flow rate of the water leaving the system.
7.5 cm
SG = 7
1.5 m
