A gasoline engine takes in 1.70×10^4J of heat and delivers 3900J of work per cycle. The heat is obtained by burning gasoline with a heat of combustion of 4.60×10^4 J/g.
Part A What is the thermal efficiency of the engine?
Part B How much heat is discarded in each cycle?
Part C What mass of fuel is burned in each cycle?
Part D If the engine goes through 56.0 cycles per second, what is its power output in kilowatts?
Part E If the engine goes through 56.0 cycles per second, what is its power output in horsepower?
