15 m 5 m 5 m 5 m 5 m A. Flow in Piping and Packed Bed In the figure, a compressor is being used to pressurize the vapor space above a liquid in a tank that is kept full to a constant level. This pressurized gas, along with the pump, provides enough energy for the fluid from the inlet tank to pass through the piping system and packed bed to the collection tank, The fluid level in the inlet tank is nearly the same as the discharge point into the collection tank. The 5 m liquid (SG = 1.2) is pumped at 30 kg/min through the 6m system. The packed bed is filled with spherical resin pellets, each 4 mm in diameter. There are 10 m of packing in the column. The void fraction for this resin is 0.43. The viscosity of the liquid is 1.5 CP. The diameter of the bed is 0.50 m. The collection tank is slightly pressurized at 3 kPa (gauge). All of the piping is smooth, 4 cm diameter. Valves add 1 m equivalent length, elbows add 1.2 m. The combined friction from the entrance and exit effects adds an equivalent pipe length of 75 cm. If the pump is 85 % efficient and able to supply half of the power necessary to move the fluid in this system, what must be the pressure of the inlet tank and the power provided to the pump?
