A rigid tank is divided into two equal parts by a partition. Initially, one side of the tank contains 5.0 kg of water at 200 kPa and 25ºC, and the other side is empty.
The partition is the removed and the water expands into the entire tank. The water
is allowed to exchange heat with its surroundings until the temperature in the tank
returns to the initial value of 25ºC. Determine:
i) the volume of the tank.
ii) the final pressure of the tank.

Athin walled concentric tube exchanger is used to cool engine oil from 160°c to 60°c with water that is available at 25°c acting as a coolant. the oil and water flow rates are each at 2 kg/s, and the diameter of the inner tube is 0.5 m and the corresponding value of the overall heat transfer coefficient is 250 w/m2. oc. how long must the heat exchanger be to accomplish the desired cooling? cpwater=4.187 kj/kg-candcpengine el=2.035 kj/kg·°c, oil . 120]
