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

Ahot wire operates at a temperature of 200°c while the air temperature is 20°c. the hot wire element is a tungsten wire of 5 um diameter and 2 mm in length. plot using excel current, heat transfer and heat generated by the wire for air velocity varying from 1-10 m/s in steps of lm/s? matlab the sensor voltage output, resistance, or assume nu 0.989 re033pr13 take air properties at tr (200°c20°c)/2 = 110°c properties of tungsten: c 0.13 kj/kg.k 3 p 19250 kg/m k (thermal conductivity) = 174 w/m.k
