- The entropy increase due to internal irreversibility is also called entropy production or entropy generation.
- The universal gas constant will be equal to difference between specific heats at constant pressure & constant volume for
- The rate of entropy increase of the control volume or the net rate of entropy transfer to it.
- The rate at which entropy is transferred out must the rate at which entropy enters the control volume.
- According to entropy principle, the entropy of an isolated system can never decrease and remains constant only when the process is reversible.
- A perfect gas having p1= 0.1 M/mm², v1=0.18 m³, T1=20°C is compressed to 1/10 of volume in an isothermal process. The change in entropy is
- During a constant pressure expansion of a gas 33.3 % heat is converted into work while the temperature rises by 20K. The specific heat of gas at constant pressure is
- A power cycle using steam as working fluid consist of i) constant pressure heat addition ii)adiabatic expansion iii) constant pressure heat rejection & iv) adiabatic compression. The cycle is
- Which of the following is true?(here pa=partial pressure of dry air, pw=partial pressure of water vapour, p=atmospheric pressure)
- Steam enters the turbine at 5.44 bar with dryness fraction of 0.9 & is expanded adiabatically to a pressure of 0.68 bar. It will enter the condenser with a quality very close to
