Question

During periods of high electricity demand, especially during the hot summer months, the power output from a gas turbine engine can drop dramatically. One way to counter this drop in power is by cooling the inlet air to the gas turbine. An increasingly popular cooling method uses high pressure inlet fogging. The performance of a sample of 67 gas turbines augmented with high-pressure inlet fogging was investigated by the Journal of Gas Turbines. One measure of performance is heat rate (in kilojoules per kilowatt per hour). Heat rates for the 67 gas turbines are provided in the file GASTURBINE.sav. Suppose that a standard gas turbine has on average, a heat rate of 10,000 kj/kwh. Conduct a test to determine if the mean heat rate of gas turbines augmented with high-pressure inlet fogging exceeds 10,000 kJ/kWh. Do not forget to state the hypothesis.
