Explanation / Answer
Adiabatic : When no heat is added or remove from system
Isochoric: no volume change of system
Isothermal: Temperature remain constant of the system
Isentropic: When entropy remain constant
Isenthalpic: when enthalpy remain constant
Reversible: system return to same position
Expansion : Volume increases
Compression: Volume decrease
Questions
1- In turbine which type of process is invole: Ans : Adiabatic
2-What are the different process involve in Carnot cycle:Ans: Isothermal expansion, Adiabatic comression,Isothermal compression,Adiabatic expansion
3-whic type of process is in flow through orifice meter to calculate flow rate from pipe :Ans: Isenthalpic
4-What is the problem in using Carnot cycle: Ans: There will be production of liquid vapor mixturein turbine, liquid causes errosion problem to turbine blade. and we can not design a pump which wil operate on liquid vapor mixture
5-What can be the improvement in Carnot cycle: Ans: Introduce Rankine cycle
6-What is the work done in isochoric process :Ans: 0 ( because dV = 0, so W = pdV
7-Why Carnot cycle is more efficient or efficiency of Carnot cycle is maximum: Ans: Because It consider the reversible path but in actual it does not happen
8-Why adiabatic prosess is also known as isentropic process: Ans: dS =dQ/T, when dQ =0 , so dS =0
9-In Which case you will get more work, Adiabatic or isothermal :Ans: Adiabatic
10-What is the efficiency of turbine: Ans: Ws/Ws(isentropic)
