A wind electric generator generates 150X.Y W at rated speed of 24 kmph at the atmospheric pressure and temperature of 20°C. Solve the percentage change of output power if the wind generator is operated at an altitude of 1800m, temperature 10°C, wind speed 30 kmph, air pressure 0.88 atmosphere, and R is the gas constant at 287 J/kg.K. Air pressure at 1 atmosphere is 1.01325 × 10³ Pa. You may make any other assumptions as required.
