- A coal power plant has a rated output of 150 MW and a first law efficiency of 41%. Coal has an energy density of 24 MJ/kg. How many metric tons of coal are wasted by the power plant per hour while running at full capacity (that is, how much of the coal that was burned did not actually contribute to generating electricity)? Express your answer in metric tons of coal.If the average household in a region consumes about 5,250 kWh of energy per year. In the region, the average annual solar energy potential is about 1,450 kWh/m² per year. If solar panels are available in sizes of 1 m x 1 m with an efficiency of 18 %, how many panels will be needed to power a house? (Since you can't have a fraction of panel, always round up you number to the next integer.) Your Answer: AnswerA standard computer has a power supply of 550 W, and many people just leave their computer on all thetime. Calculate the amount of money it costs to run a 550 W computer for 24 h, if electricity costs 7.5¢/kWh.
- A kilowatt-hour (kWh) is a unit of measure equal to one thousand watts of electricity being used in one hour. Power companies use this measurement to determine your home energy bill. Consider using a bike for power: It takes 6 minutes pedalling at 24-26 volts consistently to produce just 1/10 (0.1) of a kWh. An average home uses about 25 kWh a day. How long would someone have to pedal at 24-26 Volts to power an average home?If 370370 J of work is done on a tennis ball with an initial kinetic energy of 475475 J, calculate the final kinetic energy of the tennis ball.A demolished car weighing 15,000 N is picked up by an electromagnet on a crane in a junkyard. It lifts the car 10 meters in 4 seconds. What is the output power rating of the crane? The correct answer is 37,500 W.
