Question 1
For a system of ideal gas, in a reversible isothermal process the heat transferred to the system is 0.75 kW. The internal energy at the initial point is 2.05 kJ/s. Determine the work done during the process.
Question 2
The efficiency of Otto cycle is 60% and ratio of specific heat is 1.4.What is the compression ratio?
Question 3
A frictionless piston – cylinder device initially contains air at 100 kPa and 0.15 m3. At this state, a linear spring is attached to piston but exerts no force on it. The air is now heated to final state of 800 kPa and 0.45 m3. Then the work done against the spring is __________ (in kJ).
Question 4
An ideal gas of mass 0.5 kg has a pressure of 600 kPa, a temperature of 77
and a volume of 0.08 m3. This gas undergoes an irreversible process to a final pressure of 600 kPa and final volume of 0.12 m3, during which the heat addition and work done on gas are 2 kJ and 30 kJ respectively. The value of Cv of gas is
