A mass of 200 kg of water at 20°C is stored in a tank. An engine coupled to a propeller inside the tank transfers energy into the water causing it to heat up. What will be the water temperature after two hours with the engine running continuously? It is known that the engine power is 5 HP. (1 HP ≅ 0.75 kW). Take it out that the system has perfect thermal insulation.

Water is to be pumped from the bottom of a well 20 ft deep with a specific heat of 1 BTU/lbm F is pumped using a 1-hp jet pump. Heat is lost from the whole system at the constant rate of 500 BTU/min. What is the temperature (℉) of the water as it enters the storage tank assuming that the well water is at 35℉?
A refrigerator has a coefficient of performance of 2.50, requires 150 W of electrical power to operate, and maintains a temperature of -4.00 °C within its interior compartment. How long would it take to cool a dozen 1.00 L of water in a plastic wrapper from 33.0 °C to -4.00 °C in this refrigerator? Any heat escaping the plastic should be ignored. Remember that 1.00 g/cm3 is the density of water.
A certain system dissipates 250 BTU of heat to the surroundings. If the increase in internal energy is 222,000 ft-lbf, what is the work done? Is it done on or done by the system?
A common practice when parenting is to take a jar of baby food and place it into hot water to heat the food up. Describe this process in terms of heat transfer. Be sure to include the terms specific heat capacity, hot, cold, transfer, and thermal equilibrium.
Law of Cooling A car engine runs at a temperature of 190°F. When the engine is turned off, it cools according to Newton's Law of Cooling with constant k = 0.0341, where the time is measured in minutes. Find the time needed for the engine to cool to 90°F if the surrounding temperature is 60°F.
