Heat duty calculation of heat exchanger
Webtemperatures, the fluid properties, and the heat exchanger parameters are taken as input and the outlet temperatures and thermal duty (if the exchanger length is specified) or the required length of the heat exchanger are calculated as output. In either case, the pressure drop of each stream will also be calculated. ‘Design’ is Webfor Heat Exchanger Design & Calculations Q1 = Density x Heat capacity x ( 1 - 2 ) x 3 / 3600 [kW] Q2 = Density x Heat capacity x ( 5 - 4 ) x 6 / 3600 [kW] (For water, density is 1000, and heat capacity is 4.186kJ/kg deg.C.) The heat duty on hot side (Q1) is equal to the heat duty on cold side (Q2); Q1 and Q2 must be the same (Q1 = Q2).
