Rankine Cycle with Reheat Steam Power Plant _Turbine Work output, Thermal Efficiency & T- S Diagram

This video will demonstrates a steam power plant operates on the ideal reheat Rankine cycle. Steam enters the high pressure turbine at 8 MPa and 500 C and leaves at 3 MPa. Steam is then reheated at constant pressure to 500 C before it expands to 20 kPa in the low pressure turbine. Determine the turbine work output, in kJ/kg, and the thermal efficiency of the cycle. Also show the cycle on a T-s diagram with respect to the saturation lines.

How to set up a parametric table, re-solves for Power in & Vol.outflow rate for outlet temperatures

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.
