An internal combustion engine with a thermal efficiency of 15.0% absorbs 1.75 * 105 J absorbs of heat from the hot reservoir. How much heat is lost by the engine in each cycle?
Answer to relevant QuestionsThe heat output of a particular engine is 7.5 x 103J per cycle, and the net work out is 4.0 x 103 J per cycle. (a) The heat input is (1) less than 4.0 x 103 J, (2) between and 4.0 x 103 J and 7.5 x 103 J, (3) greater than ...When running, a refrigerator exhausts heat to the kitchen at a rate of 10 kW when the required input work is done at a rate of 3.0 kW. (a) At what rate is heat removed from its cold interior? (b) What is the COP of the ...A four-stroke engine runs on the Otto cycle. It delivers 150 hp at 3600 rpm. (a) How many cycles are in 1 min? (b) If the thermal efficiency of the engine is 20%, what is the heat input per minute? (c) How much heat is ...A Carnot engine takes 2.7 x 104J of heat per cycle from a high-temperature reservoir at 320 oC and exhausts some of it to a low-temperature reservoir at 120 oC. How much net work is done by the engine per cycle? The autoignition temperature of a fuel is defined as the temperature at which a fuel–air mixture would self-explode and ignite. Thus, it sets an upper limit on the temperature of the hot reservoir in an automobile engine. ...
