One pound-mass of water fills a 2.4264-ft3 weighted piston-cylinder device at a temperature of 6008F. The piston- cylinder device is now cooled until its temperature is 2008F. Determine the final pressure of water, in psia, and the vol- ume, in ft

Asimple speed reducer is composed of 2 spur gears. the pinion gear has a pitch diameter of 0.75" and 36 teeth while the driven gear has a pitch diameter of 4.0" and 192 teeth. a)-what is the diametral pitch of each gear? b)-if an electric motor rotating ccw at 3000 rpm is coupled to the pinion, what is the rotational speed of the driven gear? c)-if the torque delivered to the pinion is 1 n-m, what is the torque on the driven gear? d)-what is the power transmitted by the gear train?
