WebbTranscribed Image Text: Q11/ The gas-turbine portion of a combined gas-steam power plant has a pressure ratio of 16. Air enters the compressor at 300 K at a rate of 14 kg/s and is heated to 1500 K in the combustion chamber. The combustion gases leaving the gas turbine are used to heat the steam to 400°C at 10 MPa in a heat exchanger. john graves simcoe turn actorhttp://paws.kettering.edu/orgs/pbl/module3.pdf inter-american development bank bondoWebbPressure ratio is the ratio of the compressor discharge pressure and the inlet air pressure. Aeroderivative engines are derived from jet engines, as the name implies, and operate at very high compression ratios (typically in excess of 30). Aeroderivative engines tend to be very compact and are useful where smaller power outputs are needed. inter american convention on letters rogatoryGas turbine power plants are lighter and compact when compared to power plants running on vapour cycles.
