A steam engine absorbs 1.98*10^5 J and expels 1.49*10^5 J in each cycle. Assume that all of the remaining energy is used to do work.
a. What is the engine's efficiency?
b. How much work is done in each cycle?
If a gasoline engine has an efficiency of 21 percent and loses 780 J to the cooling system and exhaust during each cycle, how much work is done by the engine?
Efficiency= useful work/inputwork * 100
.21 Input work= 780J
solve for input work
thenuseful work= .79*input work
