Water at 15 ° C is flowing downward in a vertical tube 7.5 m long. The pressure is 550 k P a at the top and 585 k P a at the bottom. A ball-type check valve is installed near the bottom. The hydraulic tube is drawn steel, with a 32 mm OD and a 2.0 mm wall thickness. Compute the volume flow rate of the water.

Two pressurized prismatic tanks A and B are connected at their sides by an orifice 140 mm in diameter. Tank A contains water at a depth of 3 m above the orifice and a pressure of 50 kPa on the water surface. Tank B also contains water at a depth of 2 m above the orifice and a pressure of 15kPa on the water surface. The coefficient of discharge is 0.86 and the coefficient of velocity is 0.92.

A fluid is flowing in a horizontal pipe 8 in. in diameter with a mean velocity of10 ft/s. The pressure at the center of the pipe is 5 psi, and the elevation of thepipe above the assumed datum is 15 ft. Compute the total head in feet if the fluid is (a) water, (b) oil (SG=0.8), and (c) molasses (SG=1.5).

1A venturi meter is introduced in a 300 mm diameter horizontal pipeline carrying a liquid under a pressure of 150 kPa. The throat diameter of the meter is 100 mm and the pressure at the throat is 400 mm of mercury below the atmosphere. If 3% of the differential pressure is lost between the inlet and the throat, determine the flow rate of the pipeline.
