if there is no exponent shown, then the exponent is 1. ex: 41
Power = 5 = exponent. That is, exponent = 5.
what is the loose exponent
It is: 21a exponent 6
The word "exponent" is derived from the Latin verb "exponere", to "put out [more of something]".

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.
Isentropic process
a flow in an Isenotropic manner.

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.
The exponent.
A process takes place from initiation to completion without an increase or decrease in the entropy
if there is no exponent shown, then the exponent is 1. ex: 41
Isentropic work, i.e completely reversible work
A process takes place from initiation to completion without an increase or decrease in the entropy
