Engineering >> Chemical & Biomedical EngineeringPower Required for a Steam Compressorby Christopher Mendes
Submitted : Fall 2011 My original objective was to first gather data on the specific volume of the steam, given the interval of pressure. Once I had these values I determined that I could plot the data and fit a trend line to the data, using the excel program I also found the function for this line and integrated the function to find the work per unit mass required by the compressor to achieve such pressure. I compared my method and the trapezoidal Riemann sum method to the value I should have gotten, which was determined by the Ideal Gas Law. The results showed very little error. My second step was to do the same process as originally, yet changing the pressure form 1-10 bars to 20-200 bars. I noticed a significant change in the accuracy of my methods of integration. I thereby concluded that my two methods of integration are only accurate at low pressures. Related Links:
