An orifice meter is installed in a 6 in. ID pipeline that is inclined upward at an angle of 108 from the horizontal. Benzene is flowing in the pipeline at the flow rate of 10 gpm. The orifice diameter is 3.5 in., and the orifice pressure taps are 9 in. apart.

(a) What is the pressure drop between the pressure taps, in psi?

(b) What would be the reading of a water manometer connected to the pressure taps?
