Heat Transfer The interchange factor for radiation heat transfer from surface 'x' to surface 'y' in case of an infinite parallel planes with emis-sivities εx & εy is given by Εx + εy 1/εx + 1/εy Εx . εy (εx + εy)/(εx + εy - εx . εy) Εx + εy 1/εx + 1/εy Εx . εy (εx + εy)/(εx + εy - εx . εy) ANSWER DOWNLOAD EXAMIANS APP
Heat Transfer Log mean temperature difference (LMTD) cannot be used, if there exists an unsteady state the heat capacity is not constant and there is a phase change. none of the listed here heat transfer co-efficient over the entire heat exchanger is not constant there exists an unsteady state the heat capacity is not constant and there is a phase change. none of the listed here heat transfer co-efficient over the entire heat exchanger is not constant ANSWER DOWNLOAD EXAMIANS APP
Heat Transfer The outlet temperature of cooling water in a heat exchanger is generally not allowed to exceed above 50°C in industrial practice mainly to avoid Decrease in heat exchanger efficiency Uneconomic LMTD Excessive corrosion Its evaporation loss Decrease in heat exchanger efficiency Uneconomic LMTD Excessive corrosion Its evaporation loss ANSWER DOWNLOAD EXAMIANS APP
