Heat Transfer Hot water (0.01 m³ /min) enters the tube side of a counter current shell and tube heat exchanger at 80°C and leaves at 50°C. Cold oil (0.05 m³/min) of density 800 kg/m³ and specific heat of 2 kJ/kg.K enters at 20°C. The log mean temperature difference in °C is approximately 32 50 45 37 32 50 45 37 ANSWER DOWNLOAD EXAMIANS APP
Heat Transfer A long iron rod initially at a temperature of 20°C has one end dipped in boiling water (100°C) at time, t = 0. The curved surface of the rod is insulated so that heat conduction is one dimensional in the axial direction. The temperature at a distance 100 mm from the dipped end becomes 40°C at time, t = 200 s. The same temperature is achieved at a distance of 200 mm from the dipped end at time t = 356 s t = 283 s t = 800 s t = 400 s t = 356 s t = 283 s t = 800 s t = 400 s ANSWER DOWNLOAD EXAMIANS APP
