Water use at a thermal power plant. Thermal power plants
Chapter 13, Problem 59E(choose chapter or problem)
Water use at a thermal power plant. Thermal power plants use demineralized (DM) water for steam generation. Since it is costly to replace, power plants must conserve the use of DM water. DM water consumption was monitored at a thermal power plant in India and the results published in Total Quality Management (Feb. 2009). Plant management set the target for DM water consumption at .5%, the upper specification limit at .7%, and the lower specification limit at .1%. Based on data collected for a sample of 182 flow meter measurements, the overall standard deviation of the process was .265%. Use this information to find the capability index for this process. Interpret the result.
