A fan is designed to operate at a rotative speed of 20

A fan is designed to operate at a rotative speed of 20 rps. At the design conditions the airflow rate is 20 m3/s, the static pressure rise is 30 Pa and the air temperature is 20oC. At these conditions the fan requires a power input of 1.5 kW. Keeping the speed constant at 20 rps, if the air temperature changes to 10oC, what will be the airflow rate, static pressure and power input?
