One of the Most Efficient Engines Built So Far Has

question 23

Short Answer

One of the most efficient engines built so far has the following characteristics:
combustion chamber temperature = 1900°C
exhaust temperature = 430°C
7.0 × 10⁹ cal of fuel produces 1.4 × 10¹⁰ J of work in one hour, where 1 cal = 4.19 J
(a) What is the actual efficiency of this engine?
(b) What is the Carnot efficiency of the engine?
(c) What is the power output of this engine?
