An insulated tank is divided into two parts by a partition. One part of the tank contains 2.5 kg of compressed liquid water at 60 degrees C and 600 kPa, while the other part is evacuated. The partition is now removed, the water expands to fill the entire tank. Determine the final temperature and volume of the tank for a final pressure of 10 kPa.

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?
