Question: An engineer at Westinghouse has been charged with the responsibility of designing a gas-turbine system to deliver 40 MW of power to a small rural community. The load requirements vary from 5 to 40 MW over the course of a given day. To meet the daily load variations, the engineer has decided to vary the gas mass flow rate. The client objects to this plan, stating that this would undermine the performance of the compressor and turbine components of the system, given that these components are fluid machines like a pump or a fan. Are their concerns justified? Comment.
