Process Equipment and Plant Design In a shell and tube heat exchanger, the overall heat transfer co-efficient is proportional to the tube side (volumetric flow rate)0.8. This is valid, only when the ratio of the tube side film resistance to the total resistance is almost equal to ∞ 2 1 20.8 ∞ 2 1 20.8 ANSWER DOWNLOAD EXAMIANS APP
Process Equipment and Plant Design In the case of a shell and tube heat exchanger, the logarithmic mean temperature difference Is always less than arithmetic average value Is always less than arithmetic mean value, but more than geometric mean value May be either more or less than geometric mean and arithmetic mean value depending upon whether the flow of stream is co-current or counter-current Is always more than arithmetic mean value and the geometric mean value Is always less than arithmetic average value Is always less than arithmetic mean value, but more than geometric mean value May be either more or less than geometric mean and arithmetic mean value depending upon whether the flow of stream is co-current or counter-current Is always more than arithmetic mean value and the geometric mean value ANSWER DOWNLOAD EXAMIANS APP
