Heat Transfer Condensing film co-efficient for steam on horizontal tubes ranges from 5000 to 15000 Kcal/hr.m² .°C. Condensation of vapor is carried out inside the tube in a shell and tube heat exchanger, when the Condensate is corrosive in nature Temperature of the incoming vapor is very high Lower pressure drop through the exchanger is desired Higher condensing film co-efficient is desired Condensate is corrosive in nature Temperature of the incoming vapor is very high Lower pressure drop through the exchanger is desired Higher condensing film co-efficient is desired ANSWER DOWNLOAD EXAMIANS APP
Heat Transfer A composite wall consists of two plates A and B placed in series normal to the flow of heat. The thermal conductivities are kA and kB and the specific heat capacities are CPA and CPB for plates A and B respectively. Plate B has twice the thickness of plate A. At steady state, the temperature difference across plate A is greater than that across plate B, when KA>2 kB CPA < CPB KA < 0.5kB CPA > CPB KA>2 kB CPA < CPB KA < 0.5kB CPA > CPB ANSWER DOWNLOAD EXAMIANS APP
