Consider the formula for arc length of a sector of a circle. If we divide by time t, we obtain. This can be written as where is the linear velocity of a point on a circle or the change in arc length per unit of time, and is the angular velocity of a point on a circle or the change in radian measure per unit of time.

A water turbine with radial flow has the dimensions shown below. The absolute entering velocity is 50 ft/s, and it makes an angle of 30( with the tangent to the rotor. The absolute exit velocity is directed radially inward. The angular speed of the rotor is 120 rpm. Find the power delivered to the shaft of the turbine.

Torque and angular speed are vectors. Power is the dot product or scalar product. This formula, written without vector notation, makes the assumption that the torque and the angular rotation are around the same axes. Since power = torque x speed, power is zero at zero torque (no load speed), andpower is zero at zero speed (stall torque).

Linear Speed is distance traveled divided by time. So vB = 3vA . On the unit circle the distance traveled numerically equals the angular ‘distance’ traveled when measured in radians, but in general we’re not on the unit circle so another crucial formula is: *using rad/sec for ‘omega’… ex/ vB = 3(ft/radius) =
