4. A special oil is to be used in an absorption tower. The preliminary design of the unit requires the oil to be pumped from an open tank with a 10 ft liquid level above the floor and forced through 150 ft of 3 inches schedule 40 pipe with a ball check valve and 5 elbows into the top of a tower 30 ft above the floor. The operating pressure in the tower is to be 52 psig and the oil requirement is estimated at 50 gpm. The viscosity of the oil 15 cP and its density is 53.5 lbm/ft. Assuming the pumping outfit operates with an overall efficiency of 60%, what horsepower input will be required for the pump motor?

4. If the pressure difference between points 1 and 2 below is 90 psi, what will be the flow rate? The pipes are galvanized iron with ks = 0.0005 ft. Take kinematic viscosity equal to 1.06 x 10-5 ft²/s and neglect minor losses. 10 in dia 1. 2000 ft, 8 in dia A B 1600 ft, 6 in dia C 800 ft, 10 in dia 2.
4.32 ft 24.5 ft 7.47 ft O Air at 29.4 psig pump A pump delivers water from a lake into a 6 ft diameter by 10 foot tall sealed pressurized tank through 4 inch pipes using a 4.0 horsepower pump with an efficiency of 62%. If the head loss through the system is 6.42 ft, determine the delivery rate (m3/s) of water to the tank, for the tank level and pump pressure shown in the drawing.
Water in a constant diameter pipe is at 15m on the inlet the pipe leads to the tank situated at a height of 10m, if the total head losses are 8m and the pip inlet and outlet are exposed to the environment and the mass flow remains constant; Chose one of the following: A. no pump is required to ensure water flows to the tank B. none of the above C. a pump needs to ensure water flows to the tank D. the water will flow through gravity to the tank

3. A pump steadily circulates oil used for lubricating heavy machine tools. The volume flow rate and temperature of the oil are 300 gal/min and 104°F, respectively. At 104°F, the kinematic viscosity and the specific gravity of the oil are 2.15 x 10-3 ft² /s and 0.89, respectively. The pipe lengths are 25 ft for the 4-in diameter pipe and 75 ft for the 3-in diameter one. The Schedule-40 steel pipe has an average roughness element size of 0.0018 in. If all minor losses can be ignored, evaluate how much power (in a unit of horsepower) the pump delivers to the oil. 6 ft 22 ft Flow 15 ft Discharge line 3-in Schedule 40 Suction line 4-in Schedule 40 steel pipe steel pipe Pump
