Heat and Mass Transfer Sensible heat factor is given by (where S.H. = Sensible heat, and L.H. = Latent heat) (L.H - S.H)/S.H S.H/(S.H + L.H) S.H/(L.H - S.H) (S.H + L.H) /S.H (L.H - S.H)/S.H S.H/(S.H + L.H) S.H/(L.H - S.H) (S.H + L.H) /S.H ANSWER DOWNLOAD EXAMIANS APP
Heat and Mass Transfer Conduction is a process of heat transfer From one particle of the body to another without the actual motion of the particles From a hot body to a cold body, in a straight line, without affecting the intervening medium From one particle of the body to another by the actual motion of the heated particles None of these From one particle of the body to another without the actual motion of the particles From a hot body to a cold body, in a straight line, without affecting the intervening medium From one particle of the body to another by the actual motion of the heated particles None of these ANSWER DOWNLOAD EXAMIANS APP

Heat and Mass Transfer A designer chooses the values of fluid flow rates and specific heats in such a manner that the heat capacities of the two fluids are equal. A hot fluid enters the counter flow heat exchanger at 100°C and leaves at 60°C. A cold fluid enters the heat exchanger at 40°C. The mean temperature difference between the two fluids is 40°C 20°C 66.7°C 60°C 40°C 20°C 66.7°C 60°C ANSWER DOWNLOAD EXAMIANS APP
