A carnot engine working between `400K` and `800K` has a work output of `1200 J` per cycle . What is the amount of heat energy supplied to the engine from source per cycle?

Text Solution

Verified by Experts

`W = 1200 J, T_(1) = 8000k, T_(2) = 400 K`
`therefore " " eta = 1 - (T_(2))/(T_(1)) = (W)/(Q_(1)) implies 1-(400)/(800) = (1200)/(Q_(1))` " " 0.5 =(1200)/(Q_(1))`
Heat energy supplied by source `Q_(1) = (1200)/(0.5) = 2400` joule per cycle
