This Video shows how to solve thermodynamic problem using EES
Problem: A compressor takes in 1.2 kg/s of R-134 that is in a saturated vapor state at -24°C. The compressor outlet state is at 0.8 MPa and 100°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%. 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. No more than three sig figs for results computed for EES.
In this video, we will use a thermodynamics problem - Courtesy of ES2310 taught by Dr. Paul Dellenback
Step 1: Enter the problem information
Step 2: Use EES to obtain the values of enthalpy and density at states one and two.
Step 3: Enter the thermodynamics equations we want to solve for in EES
Step 4: Build a Parametric Table for a range of temperatures at state two.
