Question

Problem 2: Figure shows a pump and pipe network being used to transport heptane at 80F to a large, elevated storage tank that is closed, but vented to ensure that the pressure above the hetane is atmospheric. The volumetric fiow rate of the heptane is 400 gpm. (a) Determine the pressure drop (psi) that the pump must overcome Liquid level Large covered and vented storagt tank Al pipes are 6-nom sid cast iron Al fattings and valves are 6 nom Total length of straight pipe 115 to move the heptane through the discharge pipe 40 fi (b) Construct a plot that shows the variation in pressure drop as a function of the absolute roughness for values ranging from O to 0.01ft. b-nom centric butterfly valve Pump
