Benzene at 100F is being pumped from a reservoir at a rate of 40 gpm. The reservoir is at atmospheric pressure and the pump suction is 4 ft above the level of the reservoir. The friction in the suction line is 0.5 An Antoine equation for the vapor pressure of benzene shows in2 lb f log10 Py = 6.91 = ( 1211 T + 221 What is the NPSH and is kg where T is in C and pv is in mm of mercury. The density of benzene is 865 the pump suitable for service? m3. Benzene at 100F is being pumped from a reservoir at a rate of 40 gpm.
