Gasoli ne at $$20^\circ C (density = 680 kg/m^3)$$ is pumped through a smooth 12 cm diameter Pipe, 10 km long, at a flow rate of $$75 m^3/hr.$$ The inlet is fed by a pump at an absolute pressure of 24 atm. The exit is at standard atmospheric pressure and is 150 m higher. Estimate frictional head loss $$h_f$$.
