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?

Q1/
An orifice meter is to be calibrated for the measurement of the flow rate of a stream of
liquid acetone. The differential manometer fluid has a specific gravity of 1.10. The calibration
is accomplished by connecting the orifice meter in series with a rotameter that has
previously been calibrated for acetone, adjusting a valve to set the flow rate, and recording
the flow rate (determined from the rotameter reading and the rotameter calibration curve)
and the differential manometer reading, h. The procedure is repeated for several valve
settings to generate an orifice meter calibration curve of flow rate versus h. The following
data are taken.

1- For each of the given readings, calculate the pressure drop across the orifice, AP (mm
Hg).
2- The flowrate through an orifice should be related to the pressure drop across the
orifice by the formula.

The flow rate through a control valve is 10 gpm. The area of the opening of the valve is 2 in^2 andthe pressure after the valve is 10 psi. What would be the approximate pressure reading at the gaugebefore the valve? Calculate the power loss across the valve?
