The rotor of an electric motor has an angular velocity of 3600 rpm when the load and power are cut off. the 125-lb rotor, which has a centroidal radius of gyration of 9 in., then coasts to rest. knowing that kinetic friction results in a couple of magnitude 2.5 lb·ft exerted on the rotor, determine the number of revolutions that the rotor executes before coming to rest. (round the final answer to its nearest whole number.)

Air is contained in a variable-load piston-cylinder device equipped with a paddle wheel. initially, air is at 400 kpa and 17°c. the paddle wheel is now turned by an external electric motor until 75 kj/kg of work has been transferred to air. during this process, heat is transferred to maintain a constant air temperature while allowing the gas volume to triple. calculate the required amount of heat transfer in kj/kg.
