Alice wants to keep the inside of her apartment at a nice temperature of 72.6 F while the outside temperature is 87.3 F. If she were to get the internal temperature to 72.6 F and then turn off her air conditioning system, the air in the house would heat up at a rate of 3.8 kW, so when the system is on, it needs to remove heat from the apartment at the same rate to keep the temperature fixed. If the air conditioning system acts as a heat pump with coefficient of performance 1.9, what is its rate of energy consumption (in watts) while it keeps the apartment at the desired, fixed temperature
