8. The figure shows a tank within a tank, each containing air. Pressure gage A, which indicates pressure inside tank A, is located inside tank B and reads 5 psig (vacuum). The U-tube Pa 14.7 psia Tank B manometer connected to tank B contains water with a column length of 10 in. Using the data shown on the figure, determine the absolute pressure of the air inside tank B and inside tank A, both in psia. The atmospheric pressure surrounding...

Water is siphoned from a large tank and discharges into the
atmosphere through a 2-in.-diameter tube as shown in the figure
below. The end of the tube is 3 ft below the tank bottom, and
viscous effects are negligible. Determine the volume flowrate from
the tank. Determine the maximum height, H, over which the water can
be siphoned without cavitation occurring. Atmospheric pressure is
14.7 psia, and the water vapor pressure is 0.26 psia

A centrifugal pump is placed above a reservoir as shown below. If the NPSHR is 17 ft and the flow rate is 32 ft3/s, determine the maximum height, 21, that the pump can be located above the reservoir surface without cavitation. Assume that the total head loss between the tank and pump inlet is 10 ft. The diameter of the pipe on the suction side of the pump is 12 inches. The reservoir surface is at atmospheric pressure, Patm =...

Consider the process of filling a tank with compressed
air from a constant pressure supply.
Consider the process of filling a tank with compressed air from a constant pressure supply The tank has a volume of 500 ft' and initially is at atmospheric pressure and 75°F. The tank is connected to a high pressure air line that contains a control valve. The valve is quickly opened when the filling process begins, and the flow rate of...

Question 2 Water is draining from a pressurized tank as shown in the figure. The exit velocity is given by Ve=(2p/p+2gh)1/2 where p is the pressure in the tank, p is the water density, and h is the elevation of the water surface above the outlet. Constant pressure supply Control surface Exit e The depth of the water in the tank is 1.7 m. The tank has a cross-sectional area of 1.8 m2, and the exit area of the pipe...

The figure shows a cylindrical tank of 80 em in diameter which is fully filled with water. In order to increase the flow from the tank to the exit pipe on the left, an additional pressure is applied to the water surface by an air compressor to supply air to the upper air chamber of the tank. The external walls of the tank are exposed to the atmospheric conditions of the area. You are required to determine the hydrostatic conditions...
