Polytropic work calculator
WebIn practice most expansion and compression processes are somewhere in between, or said to be polytropic. The polytropic process can be expressed as. pV n = constant (3a) or . p 1 … Webconsider two instances (p1,v1) and (p2,v2) with some time interval. If there is no heat addition then p2v1 the we will get some value for polytropic index.

WebCalculation methods prescribed in ASME PTC 10-1997 and ISO 5389 are largely based upon the pioneering work of Schultz (1962) in his paper entitled "The Polytropic Analysis of Centrifugal Compressors" which presents a development of both isentropic and polytropic methods for compressor test evaluation, selection and design.
A polytropic process is a thermodynamic process that obeys the relation: where p is the pressure, V is volume, n is the polytropic index, and C is a constant.
