Question

Filling a pressurized vessel. Determine the net power (W − Ev) in kW needed to be supplied by the pump in the figure below to pump liquid benzene (ρ = 0.877 g/cm3, μ = 0.647 cp) at a rate of 2.25 gal/sec. Assume atmospheric pressure is Po = 1.0 atm, and the inner diameter of the pipe is D = 0.425 in. What is the Reynolds number, NRe, for this process? (Assume a “hydraulically smooth” interior surface for the pipe).

Liquid benzene 10 ft Nitrogen gas pocket Pr 5.5 atm 3 ft
