Answer to Question #130389 in Chemical Engineering for Kea

Question

The overhead condensate from a distillation column of density 0.6 g/cm3 and viscosity 0.6 x 10-4 Pas is fed at a rate of 300 kg/min from the condensate drum held at a gauge pressure of 12 bar to a pressurized storage vessel at a gauge pressure of 10.2 bar prior to further processing. The pipeline has a length of 2.5 km and an inside diameter of 7.5 cm with a wall roughness of 0.046 mm. If the difference in level of the condensate in the condensate drum and the discharge of the pipe into the storage vessel is 1 m, determine the power requirement of the pump and the motor assembly if their combined efficiency is 65%. Allow for entrance and exit losses and where the pipe contains fifty-six 90o elbows of 0.7 velocity heads each and four open gate valves of 0.15 velocity heads each
