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 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 mean value, but more than geometric mean value Is always less than arithmetic average 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
Process Equipment and Plant Design Heat transfer co-efficient, hG(Kcal/hr.m² .°C) and mass velocity of air, G (kg/hr.m² ) for air flow parallel to the surface in case of constant drying rate in batch drying is related as hG = 0.0176G0.8. But when the flow of air perpendicular to the surface is encountered, this equation changes to 1.004G0.8 HG = 0.0176G0.37 0.0176G1.37 HG = 1.004G0.37 1.004G0.8 HG = 0.0176G0.37 0.0176G1.37 HG = 1.004G0.37 ANSWER DOWNLOAD EXAMIANS APP
