Question: If an engine does 200 J of net work and
If an engine does 200 J of net work and exhausts 800 J of heat per cycle, what is its thermal efficiency?
Answer to relevant QuestionsA gasoline engine has a thermal efficiency of 28%. If the engine absorbs 2000 J of heat per cycle, (a) What is the net work output per cycle? (b) How much heat is exhausted per cycle? A steam engine is to have its thermal efficiency improved from 8.00% to 10.0% while continuing to pro-duce 4500 J of useful work each cycle. (a) Does the ratio of the heat output to heat input (1) increase, (2) remain the ...A steam engine has a thermal efficiency of 15.0%. If its heat input for each cycle is supplied by the condensation of 8.00 kg of steam at 100 oC. (a) What is the net work output per cycle, and (b) How much heat is lost to ...What is the Celsius temperature of the hot reservoir of a Carnot engine that is 32% efficient and has a 20 oC cold reservoir? An ideal gas expands from 1.0 m3 to 3.0 m3 at atmospheric pressure while absorbing of heat in the process. (a) The temperature of the system (1) increases, (2) stays the same, (3) decreases. Explain. (b) What is the change ...
