Answer in brief.
What sets the limits on the efficiency of a heat engine?
The figure shows the V-T diagram for one cycle of a hypothetical heat engine which uses the ideal gas. Draw the p-V diagram diagram of the system.
What are the processes involves in a Carnot engine?
Explain the heat engine and obtain its 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 ______.
A heat engine operates between a cold reservoir at temperature T2 = 400 K and a hot reservoir at temperature T1. It takes 300 J of heat from the hot re ervoir and delivers 240 J of heat to the cold reservoir in a cycle. The minimum temperature of the hot reservoir has to be ______ K.
What does a heat engine consist of?
