The value of polytropic exponent 'n' in the reversible polytropic process usually varies between?
1.2 to 1.4
What is polytropic process?
A polytropic process is a process where ( P ) ( V )^n is maintained throughout the process; commonly a compression or an expansion. The n is called the polytropic exponent and is often between 1.0 and k , the specific heat ratio. For a reversible, polytropic, and nonflow process : WB = [ ( P2 ) ( V2 ) - ( P1 ) ( V1 ) ] / [ 1 - n ] or WB = [ 1 / 1 - n ][ ( P1 ) ( V1 ] [ ( P2 / P1 )^B - 1 ] B = ( n - 1 ) / ( n ) For a reversible, polytropic, and steady flow process : WSF = [ n / 1 - n ] [ ( P1 ) ( V1 )] [ ( P2 / P1 )^B - 1 ] B = ( n - 1 ) / ( n )
What is the difference between isothermal and hyperbolic 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.
What is flow and non flow process of themodynamic's?
flow process : it is one in which fluid enters the system and leaves it after work interaction,which means that such processes occur in the systems having open boundary permitting mass interaction across the system boundary. non flow process : it is the one in which there is no mass interaction across the system boundaries during the occurrence of process. different type of non flow process of perfect gas are given below: (1) constant volume process (2) constant pressure process (3) Isothermal process (4) adiabatic process (5) polytropic process
What is isobaric process?
The process in which change in volume and temperature takes place at a constant pressure is called an isobaric process
What is the value of polytropic exponent n in reversible polytropic process?
the value of polytropic exponent "n" in reversible process will vary from 1 to adiabatic constant "gamma"

What is net heat change in polytropic process?
q=c(T2-T1)
Derivation of polytropic equation of state?
See wikipedia article on polytropic processes.
Which process will lead to larger work output isothermal process or polytropic process with n1.25?
The process equation for this is PV up to the nth power which equals C. The polytrophic process is 1.25 which is the n in the equation.
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.

The elements of the earth are in a constant process of being?
constant process of being used.
What are the thermodynamic polytropic processes?
for isen tropic process the heat transfer(Q) will zero. for poly tropic process is heat transfer not equal to zero
Is piston cylinder process is constant pressure process or constan volume process?
A piston cylinder process actually includes two processes. The gas inside the piston undergoes both the constant pressure process and the contant volume process.
