Practically there is no reversible isentropic process but to make the concept easier to be understood, you have to assume the following:
* Ideal gas.
* no friction losses.
* Adiabatic preocess (no heat gain, no heat loss).
API 520 part 1 Appendix B assumes that the vapor expansion through a nozzle or a pressure relief valve follows an isentropic path.

What is another name for riversible adiabatic process?
Isentropic process
What is the difference between isentropic and isenthalpic expansion?
isenthalpic expansion is through PRDS or control valve where entropy changes. Whereas expansion through a steam turbine is isentropic one and enthalpy drops. isentropic expansion is more efficient process as compared to isenthalic one.
What do natural process tend to increase?
entropy of thermodynamic systems
A quantity that gives the direction of a thermodynamic process is?
specific heat
Is heat a thermodynamic function?
what is heat a thermodynamic function
What is another name for riversible adiabatic process?
Isentropic process
What is isentropic process?
A process takes place from initiation to completion without an increase or decrease in the entropy

What is an adiabatic process?
An adiabatic process is a thermodynamic process, there is no gain or loss of heat.
What do natural process tend to increase?
entropy of thermodynamic systems
A quantity that gives the direction of a thermodynamic process is?
specific heat
What is an isoentropic process?
An isoentropic process is a chemical or thermodynamic process in which entropy does not change. An example a reversible adiabatic process is isoentropic.
What is hyperbolic process in thermodynamic process?
At engineering level technically both process are same except there definition both process give hyperbolic curve in P-V diagram and straight line in T-S diagram. and even in polytropic process PV^n=constant if n=1 then it is not hyperbolic process it is isothermal process even though the definition says pv=c is hyperbolic process.
Which thermodynamic process gives maximum work?
Reversible adiabatic expansion/compression
What is the isentropic exponent of water?
5
What are the main domestic uses for gas water heaters?
A gas water heater is used to produce hot water in a thermodynamic process. The use of hot water in a domestic environment includes cooking, cleaning, bathing and heating.
