Process Equipment and Plant Design In the case of a shell and tube heat exchanger, the logarithmic mean temperature difference 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 average value Is always less than arithmetic mean value, but more than geometric mean 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 average value Is always less than arithmetic mean value, but more than geometric mean value Is always more than arithmetic mean value and the geometric mean value ANSWER DOWNLOAD EXAMIANS APP
Process Equipment and Plant Design Ponchon Savarit method is based on the use of enthalpy concentration diagram, which contains the bubble point curve (saturated liquid curve), dew point curve (saturated vapour curve) and equilibrium tie lines. As compared to McCabe-Thiele's method, this method All of these Accounts for the enthalpy changes in the process Facilitates direct calculation of heat load on reboiler & condenser from, the diagram used in this method Is more accurate in finding the number of equilibrium stages All of these Accounts for the enthalpy changes in the process Facilitates direct calculation of heat load on reboiler & condenser from, the diagram used in this method Is more accurate in finding the number of equilibrium stages ANSWER DOWNLOAD EXAMIANS APP
