The figure shows a pump and pipe network being used to transport heptane at 140 °F to a large, elevated, closed storage tank. The tank is pressurized and maintained at 18 psia. The volumetric flow rate of the heptane is 500 gpm. Determine the pump discharge pressure required (psia) to move the heptane through the discharge pipe. 

Note: Utilize 3k method.
