Mechanisms of heat transfer

Heat transfer is an essential discipline in thermal engineering that deals with the transfer, conversion, usability, and creation of heat or thermal energy. Transfer of heat occurs through various mechanisms like conduction, convection, radiation, and change of phases. All these mechanisms have distinct characteristics, but these mechanisms can simultaneously occur in an identical system.

If you have a flat tire and need to pump up the tire on your car with a hand pump, what force do you have to apply to the pump handle? Assume the air pressure in your tire will be 20 lb/in2, that is 1.1 KPa (138,0000 N/m2). Let the air pump have a cross-section that is 5 cm in diameter. It depends on the weight of the car. About 270 N when the tire is full, not much when you start pumping on the empty tire. About 270 N for as long as it takes from the beginning. Just a few newtons until you are satisfied with how full the tire is because of the hand pump.
