9. Pumping kerosene - M. Fig. P3.9 shows how nitrogen gas under a pressure P, - 15.0 psig can be used for "pumping" kerosene at 75 °F (p 51.0 lb,/ft',

u 4.38 lbm/ft hr) through an elevation increase of 20 ft. If there is an effective length (including fittings) of 150 ft of nominal 2-in. pipe between the two tanks, what is the flow rate of kerosene in gpm? Neglect exit kinetic-energy effects.
