Abstract
Mathematical procedure for estimating Joule- Thompson coefficient η, heat capacity ratio γ and Shaft work done WS using CV, CP, z, R as precursor parameters for calculation is presented. The research significance lies on its applications as a quick check for these parameters by design engineers during design of some process plant units’ i.e compressors, reactors, refrigeration system, power plant and utilities, piping systems etc. The method gave acceptable deviation that can be applied in process designs. They are shaft work done 10.6%, heat capacity ratio 1.42% and Joule- Thompson coefficient 2.05%.
