Determine the work required to pump liquid isopropanol (density = 786 kg/m3 , dynamic viscosity = 2.012 mpa-s) from a holding tank to continuous stirred-tank reactor (cstr) with a 90% efficient pump at a volumetric flow rate of 1000 m3 /hr. through 42 meters of 0.3-m diameter commercial steel pipe (e = 0.00015 ft.) with an open gate valve and four standard 90-degree elbows. the holding tank and cstr are both open to the atmosphere, but the cstr is 2-m above the holding tank
