How to calculate fan shaft power
WebThe following is a generic equation to determine the required horsepower to drive the fan or blower element . This equation does not compensate for temperature, density or airflow … WebThrust Power Generation of thrust in flight requires the expenditure of power. For a propeller or a jet-engine fan, the shaft power and the thrust are related by the definition of propeller efficiency. TV Pshaft ≡ Pprop Pshaft ≡ ηprop (1) The ηprop is the product of a viscous profile efficiency ηv which accounts for the viscous profile
