WebWe can use the air tables to find the specific heat capacity, and the equations for isentropic and polytropic processes to calculate the other properties. ... Calculate the net work output and the thermal efficiency of the cycle. Explanation: Please refer to the above step . View the full answer. Step 2/5. Step 3/5. WebThe heat transferred to the system equals the work times the ratio of the polytropic index minus the heat capacity ratio and heat capacity ratio minus 1. The entropy change equals the product of the logarithm of the ratio between the final and initial temperatures, isobaric heat capacity and the ratio of the polytropic index minus the heat capacity ratio and heat …

Web1 day ago · For a closed system, the first law is written as −. Σ Q = Σ W. But this is only valid for a closed system which is undergoing a cycle. For a process it can be written as −. Q 1 − 2 = U + W 1 − 2. Before we can start modelling these one should know how to model work and heat for different processes. So let us do that first. WebIn a polytropic process, the compression or expansion process takes place in small steps (infinitesimally small steps). Calculating the work for the polytropic process involves the summation of the work for each step. To calculate the work for each infinitesimal step, we use the isentropic analysis discussed in Section 2.8.2. WebAug 27, 2011 · Finally, the Eqn.1 is used for calculating the work done by the system as W=0.59564 KJ The methodology used by the above sample problem can be used for … granular traction ag
