3.59              Cooling method for gas turbines. Refer to the Journal of Engineering for Gas Turbines and Power (January 2005) study of the performance of a gas turbine engine cooled by high pressure inlet fogging, Exercise 1.62 (p. 51). Recall that 67 gas turbines augmented with high pressure inlet fogging were tested and the heat rate (kilojoules per kilowatt per hour) of each measured. Among the other variables measured was speed (revolu- tions per minute) of the engine. The data for the 67 engines are saved in the GASTURBINE file

(with selected observations shown in the table on the previous page.). Consider a straight-line model relating heat rate (y) to speed (x). Conduct a com- plete simple linear regression analysis of the data. Interpret the results.
