Energy Equation for the compressor shown in Figure 1: mm 1(h 1 + pp 1 ee + kk 1 ee) + WW ss = QQ + mm 2(h 2 + pp 2 ee + kk 2 ee) + dddd dddd cccc Fig. Solution: First let s solve the problem by hand so we can compare to the EES results. No more than three sig figs for results computed for EES. Then, set up a parametric table that re-solves for both the power input and volumetric outflow rate for outlet temperatures: 180, 160, 100, and 80 C. Find: The power input of R-134 by the compressor, the volumetric flow rate at the exit and how much power must be provided by an electric motor if the compressor s efficiency is 70%. ![]() The compressor outlet state is at 0.8 MPa and 100 C. Problem Solution Given: A compressor takes in 1.2 kg/s of R-134 that is in a saturated vapor state at -24 C. The solution to the problem is shown below to help the reader better understand the problem before it is solved in EES. Paul Dellenback in the fall semester of 2014) to better understand how the program EES can be used to help solve problems. 1 Engineering Equation Solver (EES) Tutorial In this tutorial, we will use a thermodynamics problem (courtesy of ES2310 taught by Dr.
