This formula uses 5 Variables
Variables Used
Power - (Measured in Watt) - Power is defined as the product of thrust force and velocity of aircraft.
Weight of Body - (Measured in Newton) - Weight of Body is the force acting on the object due to gravity.
Freestream Velocity - (Measured in Meter per Second) - The Freestream Velocity is the velocity of air far upstream of an aerodynamic body, that is before the body has a chance to deflect, slow down or compress the air.
Drag Coefficient - Drag Coefficient is a dimensionless quantity that is used to quantify the drag or resistance of an object in a fluid environment, such as air or water.
Lift Coefficient - The Lift Coefficient is a dimensionless coefficient that relates the lift generated by a lifting body to the fluid density around the body, the fluid velocity and an associated reference area.
