A gasoline engine has a thermal efficiency of 25.0%. If heat is expelled from the engine at a rate of 1.50 x 106 J/h, how long does the engine take to perform a task that requires an amount of work of 1.5 x 106 J?
Answer to relevant QuestionsA 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 ...What is the Celsius temperature of the hot reservoir of a Carnot engine that is 32% efficient and has a 20 oC cold reservoir? A heat engine operates at a thermal efficiency that is 45% of the Carnot efficiency. If the temperatures of the high-temperature and low-temperature reservoirs are 400 oC and 50 oC, respectively, what are the Carnot ...Equation 12.15 shows that the greater the temperature difference between the reservoirs of a heat engine, the greater the engine’s Carnot efficiency. Suppose you had the choice of raising the temperature of the ...A Carnot engine is to produce 100 J of work per cycle. If 300 J of heat is exhausted to a 27oC cold reservoir per cycle, what is the change in entropy of the hot reservoir per cycle?
