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 mean value, but more than geometric mean value Is always less than arithmetic average value Is always more than arithmetic mean value and the 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 less than arithmetic mean value, but more than geometric mean value Is always less than arithmetic average value Is always more than arithmetic mean value and the 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 ANSWER DOWNLOAD EXAMIANS APP
Process Equipment and Plant Design In a shell and tube heat exchanger, triangular pitch arrangement as compared to square pitch arrangement Can accomodate less number of tubes for a given shell diameter Facilitates easier shell side cleaning; hence is more suitable for handling high dirt factor shell side fluid Results in higher shell side pressure drop Creates relatively lower turbulence on the shell side resulting in lower shell side heat transfer co-efficient Can accomodate less number of tubes for a given shell diameter Facilitates easier shell side cleaning; hence is more suitable for handling high dirt factor shell side fluid Results in higher shell side pressure drop Creates relatively lower turbulence on the shell side resulting in lower shell side heat transfer co-efficient ANSWER DOWNLOAD EXAMIANS APP
