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 flow rate of the heptane is 400 gpm. (a) Determine the pressure drop (psi) that the pump must overcome to move the heptane through the discharge pipe (b) Construct a plot that shows the variation in pressure drop as a function of the absolute roughness for values ranging from 0 to 0.01ft. Liquid level 40 ft Large covered and vented storage tank All pipes are 6-nom sid cast iron All fittings and valves are 6 nom Total length of straight pipe = 115 f 6-nom centric butterfly valve tratt Pump
