Tangential Velocity of Impeller at Inlet Formula

Tangential Velocity of Impeller at Inlet = pi*Diameter of centrifugal pump impeller at inlet*Angular velocity of centrifugal pump/60
u1 = pi*D1*N/60

What is tangential velocity?

Tangential velocity is the linear speed of any object moving along a circular path. In this case the inlet pipe is axial and therefore fluid enters the impeller with very little whirl or tangential component of velocity and flows outwards in the direction of the blades.
