A submersible pump of 80 percent efficiency is used in pumping water with flow rate,Q from a river to a pool at an elevation, h. The frictional losses is assumed with losscoefficient, K = 10. By the aid of a labelled diagram, derive an expression on thepower require to drive the pump.
A steady stream of n-butanol is needed to be fed into the reactor at 40 ̊C. However, the inlet of the reactor is located 7.5 m above the reservoir tank. As such, a highly effective centrifugal pump (70% efficiency) is used for such a purpose. It was understood that the needed volumetric flow rate into the reactor is fixed at 20 m3/h. It was also noted that the n-butanol reservoir is closed but not pressurized, while the gauge pressure at the endof the discharge line is measured at 275 kPa. Given that the density of n-butanol is 810kg/m3. If the discharge pipeline was 5 cm in diameter, calculate: (i) The velocity of n-butanol at the discharge line. (ii) The total power input from the centrifugal pump. (iii) The power delivered to the n-butanol fluid.
