PTU HEAT TRANSFER QUESTION PAPER SOLUTION-SECTION-A Solution of university question is very helpful. It increases the clarity and understanding. Thus the knowledge is applied easily in practical applications. Q 1. Write briefly: (a) What is conduction shape factor? ANS: Conduction shape factor will be there for a plain wall, cylindrical body and a spherical […]
MASS TRANSFER CLASS NOTES FOR ENGINEERING Before discussing convective mass transfer, it is necessary to compare convective heat transfer and convective mass transfer since there is a similarity between these two. In heat transfer, there is convective heat transfer coefficient ‘ h’. Similarly there is mass transfer coefficient in mass transfer. Prandtl number (Pr […]
CONVECTION HEAT TRANSFER CLASS NOTES FOR MECHANICAL ENGINEERING Convection heat transfer is of two types. That is free and forced convection. Free convection starts in stationary fluids. Forced convection heat transfer is in moving fluids. Motion is caused by a pump or a fan. It takes place in fluids (liquids, vapors and gases). Convection is […]
FIN HEAT TRANSFER CLASS NOTES FOR MECHANICAL ENGINEERING Fin is a solid extended surface or a combined conduction convection system. Heat is transferred by Conduction within the solid and by convection from the fin surface in a PERPENDICULAR direction to that of conduction. Finally heat is lost to the surroundings. Fins increase the rate of heat […]
