Answer in brief.
What sets the limits on the efficiency of a heat engine?
Explain the heat engine and obtain its efficiency.
Derive the expression for Carnot engine efficiency.
Suppose a person wants to increase the efficiency of the reversible heat engine that is operating between 100°C and 300°C. He had two ways to increase efficiency.
- By decreasing the cold reservoir temperature from 100°C to 50°C and keeping the hot reservoir temperature constant
- by increasing the temperature of the hot reservoir from 300°C to 350°C by keeping the cold reservoir temperature constant.
Which is the suitable method?
A Carnot engine whose efficiency is 45% takes heat from a source maintained at a temperature of 327°C. To have an engine of efficiency of 60% what must be the intake temperature for the same exhaust (sink) temperature?
Heat engine transfers ______.
Let η1 is the efficiency of an engine at T1 = 447°C and T2 = 147°C while η2, is the efficiency at T1 = 947°C and T2 = 47°C. The ratio `eta_1/eta_2` will be ______.
What is a heat engine?
Mention any two elements of a heat engine.
