Temperature increase after supply fan is it the energy added by electrical energy used by fan or increase in velocity?

[@dhyandpatel132]

Hey, thank you for your intriguing question. Energy added is by both the sources. One is due to thermodynamic principle, as fan increases pressure and velocity, the basic thermodynamic principle says since the volume remains same, the temperature has to increase. But actually, the increase in pressure due to fan is very low. Fan's purpose is to move air, while compressor increases pressure. Secondly, as the electrical power does into fan's motor, there is lot of heat generated in motor. Usually motor is in path of air stream, hence the motor heat is absorbed by air. The fan temperature rise calculated here is based on the heat added from motor. I hope the thing is clearer. If you have any such query, please comment. I am happy to discuss.
