A gasoline engine takes in 170times104j of heat and, Ask an Expert

Academics

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?
