3. A refrigerator with a power of 450W and a COP of 1.5 is used to cool 5 watermelons of 11kg each at 8°C. If the watermelons are initially at 28°C, determine how long it will take the refrigerator to chill them. Watermelons can be treated like water with a specific heat of 4.2kJ/kg°C. Discuss whether your answer is realistic or optimistic. Hint: Use the temperature difference of the watermelons and the heating value to determine the energy required to remove them in KJ.
THERMOFLUID A student living in a 3-m X 4-m X 4-m dormitory room turns on her 100-W fan before she leaves the room on a summer day, hoping that the room will be cooler when she comes back in the evening. Assuming all the doors and heat trans windows are tightly closed and disregarding any heat fer let through the walls and the windows, determine the temperature in the room when she comes back 8 h later. Use specific heat values at room temperature, and assume room to be at 100 kPa and 20°C in the morning she leaves.
