Question
Consider a room that is initially at the outdoor temperature of 20 C. The room contains a 60-W light bulb, a 3000-W electric oven, a 400-W TV set and two 300-W fridge. Assuming no heat transfer through the walls, determine the rate of increase of the energy content of the room when all of these electric devices are on.

In the previous activity you also considered a situation in which a person turned a generator, which in turn lit a bulb. The G/R diagram for this situation is shown below, with a dashed box showing a system consisting of the person, generator, bulb, light receivers and the surroundings. The appropriate values for energy transfers and changes are also shown.

- Consider a water-to-water counter-flow heat exchanger with these specifications. Hot water enters at 95°C while cold water enters at 20°C. The exit temperature of hot water is 15°C greater than that of cold water, and the mass flow rate of hot water is 50 percent greater than that of cold water. The product of heat transfer surface area and the overall heat transfer coefficient is 1400 W/K. Taking the specific heat of both cold and hot water to be cp = 4180 J/kg·K, determine (a) the outlet temperature of the cold water, (b) the effectiveness of the heat exchanger, (c) the mass flow rate of the cold water, and (d) the heat transfer rate.arrow_forwardAn insulated 40-ft3 rigid tank contains air at 50 psia and 120°F. A valve connected to the tank is now opened, and air is allowed to escape until the pressure inside drops to 25 psia. The air temperature during this process is maintained constant by an electric resistance heater placed in the tank. Determine the electrical work done during this process.arrow_forwardSuppose that you have left a 200 mL cup of coffee sitting until it has cooled to 30◦ C, which you find totally unacceptable. Your microwave oven draws 1100W of electrical power when it is running. If it takes 45s for this microwave oven to raise the temperature of the coffee to 60◦ C, what is the efficiency of heating with this oven? You will need to use the fact that 4.2 J of energy is required to raise the temperature of 1.0 mL of coffee by 1.0◦ C.arrow_forward
- PROBLEM 4 A heat pump is used to meet the heating requirements of a house and maintain it at a comfortable temperature. On an average winter day, the house is estimated to lose heat at a rate of 80,000 kJ h¯¹. The heat pump has a COP of 2.5 under these conditions.

- Question 10. A detective has been called to the scene of a crime where a dead body has just been discovered. The detective arrives at 9:00 AM and begins to investigate. Immediately, the temperature of the body is taken and is found to be 90.3°F. The detective checks the programmable thermostat and finds that the room has been kept at a constant 68.0°F for the past 3 days. After the evidence from the crime scene is collected, the temperature of the body is taken once more and found to be 89.0°F. This last temperature reading was taken exactly one hour after the first one. The following day, the detective is asked "At what time did our victim die?" Assuming that the victim's body temperature was normal (98.6°F) prior to death, what should the detective answer?arrow_forwardTo keep warm outdoors, your run a 1118W generator for 4 minutes to make yourself a 300mL cup of tea.

In order to keep the water in the container heated to a constant temperature of 35.0°C you adjust the temperature of the spherical heater. You reach a steady-state condition when the surface temperature of the spherical heater is at 79.0°C. Assuming the electrical efficiency of the heater is 100.0%, calculate the power required by the heater (i.e., calculate q). Ignore radiation.arrow_forward
