here is the question.

A gasonline engine has a power output of 180 kW (241hp). Its thermal efficiency is 28%.

a) How much heat must be supplied to the engine per second?

b) How much heat is discarded by the engine per second?

I know this is probably a simple question, but I am kind of having a hard time with this chapter. I know that thermal efficiency is equal to work/Qh...and after that...i need a little help. Thanks for any help.
