Find the heat given( in KJ) to the feed for the flash vaporization process if the ratio of residue to the distillate is 0.65 and the enthalpy of feed, distillate and the residue are 500, 800 and 200 KJ/kmol respectively. The feed rate is 100 kmol/hr.

Find the heat given( in KJ) to the feed for the flash vaporization process if the ratio of residue to the distillate is 0.65 and the enthalpy of feed, distillate and the residue are 500, 800 and 200 KJ/kmol respectively. The feed rate is 100 kmol/hr. Correct Answer 6363

-W/D = (HD-(Hf+Q/f))/ (Hw- (Hf+Q/F)) On apply the values, we get 6363 KJ

In a surface condenser, the water flowing through a series of tubes at the rate of 200 kg/hr is heated from 15 degree Celsius to 75 degree Celsius. The steam condenses on the outside surface of tubes at atmospheric pressure and the overall heat transfer coefficient is estimated at 860 k J/m2 hr degree. Find the effectiveness of the heat exchanger. At the condensing pressure, stream has a saturation temperature 0f 100 degree Celsius and the latent heat of vaporization is 2160 k J/kg. Further, the steam is initially just saturated and the condensate leaves the exchanger without sub-cooling i.e. only latent heat of condensing steam is transferred to the water. Take specific heat of water as 4 k J/kg K
