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 = 400 s t = 283 s t = 800 s t = 356 s t = 400 s t = 283 s t = 800 s ANSWER DOWNLOAD EXAMIANS APP
Heat Transfer For the same heat load and mass flow rate in the tube side of a shell and tube heat exchanger, one may use multipass on the tube side, because it Decreases the outlet temperature of cooling medium Decreases the pressure drop None of these Increases the overall heat transfer coefficient Decreases the outlet temperature of cooling medium Decreases the pressure drop None of these Increases the overall heat transfer coefficient ANSWER DOWNLOAD EXAMIANS APP
