Power to be supplied.
 

Dear Friends, There is a cylinder of 5 mm dia, 350 mm in length.. If air flows over it with 5m/sec velocity, and if the air-inlet temperature is 25C, find the power to be supplied to heat the air to 40C ? Assume the resistance of cylinder surface material if required and mention that. Kindly let me know the book which u r goin to refer. Thank you.
