Characteristic curves are available for a fan running at 850rpm and passing air of inlet density 1.2 kg/m3. Readings from the curves indicate that at an airflow of 150 m³ /s, the fan pressure is 2.2 kPa and the shaft power is 440 kW. If the efficiency remains unchanged, calculate the corresponding points if the fan is run at 1100 rpm in air of density 1.1 kg/m3.
