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 Ibm/ft. Assuming the pumping outfit operates with an overall efficiency of 60%, what
horsepower input will be required for the pump motor?
Explain briefly Pressure-spring
thermometer
With the use of suitable schematics, describe how a manometer can be used to measure the pressure in an installed pipeline
