A pumping station wet well operates between 540- and 550-ft elevation. The pump curve is deϐined by the following points: 80 ft at zero ϐlow, 78 ft at 200 gpm, 65 ft at 800 gpm, and 50 ft at 1200 gpm. The pump discharge contains an equivalent of 50 ft of 6-in. pipe.

SOLVES TEP BY STEP DONT USE CHATGPT DONT USE AI 3. An oil of viscosity 1.8 cp and relative density 0.8 is contained in an open tank located above the application site. A 1.5-inch diameter pipe extends vertically from the bottom of the tank and is 5 m long. The oil level in the tank remains constant at 3 m above the bottom of the tank. In a case with friction the discharge speed can be obtained in the form of the following Equation. Calculate the flow rate of oil discharged per hour. Assume that the pipe is commercial steel (ε=0.05 mm). V= 2gh +f-

Water is stored in a tank sketched in the figure below to support the demand of a nearby community area.The system is designed so that pressure at the location B always lies in the range of 330 to 440 kPa (gauge).Water demand fluctuates between 0.3 and 1 m3/s regardless of pressure at B. The supply pipe of 600 mmdiameter and 1 km length between A and B is made of steel and has the equivalent sand roughness of 1 mm.Although not shown in the figure, the supply pipe has five 90◦ bends, each having the head loss coefficientof 0.8. The figure shows that the bottom end of the tank is located 42 m above the ground, and the pipe isburied 1.5 m below the ground. A pump system regulates so that the tank keeps the same water level all thetime. Assume water at 20◦C, and air in the storage tank has the atmospheric pressure. To meet the designcriterion for pressure at B, what should be the depth of water h in the storage tank?
