A 2 in. sch 40 pipe is carrying water at a flow rate of 8 gpm. The flow rate is measured by means of an orifice with a 1.6 in. diameter hole. The pressure drop across the orifice is measured using a manometer containing an oil of SG 1.3.

(a) What is the manometer reading in inches?

(b) What is the power (in hp) consumed as a consequence of the friction loss due to the orifice plate in the fluid?
