WebHeat engine is a device which converts heat into useful mechanical energy. It does this by bringing a working substance from a higher state temperature to a lower state temperature. A heat "source" generates thermal energy that brings the working substance to the high-temperature state. The working substance generates work in the "working body ... WebTo determine the efficiency, we need to find Q H. Hence, we need to use the heat transferred and the work to calculate it. Then, we can use the efficiency formula to calculate efficiency, using heat lost Q H and work. Q H = Q C + W = 1920 + 400 = 2320 J η = W Q H = 400 / 2320 = 0. 1724 η % = 0, 1724 · 100 = 17, 24 %. leadwort leaf https://yangconsultant.com
