The figure shows the vanes of a centrifugal-pump impeller which turns with a constant clockwise speed of 200 rev/min . The fluid particles are observed to have an absolute velocity whose component in the r-direction is 10 ft/sec at discharge from the vane. Furthermore, the magnitude of the velocity of the particles measured relative to the vane is increasing at the rate of 80 ft/sec² just before they leave the vane. Determine the magnitude of the total acceleration of a fluid particle an instant before it leaves the impeller. The radius of curvature p of the vane at its end is 8 in.
