Suppose a 15-foot diameter packed column is to be used for a separation. The column required 21.09 equilibrium stages and a partial reboiler. The column uses ceramic 1-inch Intalox saddles that have an HETP of 0.370 m. Pressure is 101.3 kPa. Estimate a. The total height of the tower b. Volume of tower c. Packing cost d. Tower cost

Liquid flows at steady state at a rate of 2 lb/'s through a pump, which operates to raise the elevation of the liquid 100 ft from control volume inlet to exit. the liquid specific enthalpy at the inlet is 40.09 btu/lb and at the exit is 40.94 btub. the pump requires 3 btu/s of power to operate. if kinetic energy effects are negligible and gravitational acceleration is 32.174 tt/s, the heat transfer rate associated with this steady state process is most closely 1)-2,02 btu/s from the liquid to the surroundings 2)-3.98 btu/s from the surroundings to the liquid. 3)-4.96 btu/s from the surroundings to the liquid. 4)-1.04 btu/s from the liquid to the surroundings.
