Example(5) A fan having an efficiency of 0.65 is used to suck air from a room and then push it through a duct system, where a grill is installed at the end of duct to distribute the air delivered. Consider that the airflow rate through the duct is 1m/s, while the equivalent diameter of the duct is 335 mm. If the grill causes a pressure drop of 30 Pa and the static pressure drop along the duct and elbows is 110.25PA, calculate the fan power.

Example(5) A fan having an efficiency of 0.65 is used to suck air from a room and then push it through a duct system, where a grill is installed at the end of duct to distribute the air delivered. Consider that the airflow rate through the duct is 1m'/s, while the equivalent diameter of the duct is 335 mm. If the grill causes a pressure drop of 30 Pa and the static pressure drop along the duct and elbows is 110.25Pa, calculate the fan power.
