The object of the tests was to find the head, brake horsepower, and efficiency, vs. flow rate relationships for the Mark 40 pumpjet in the normal pumping, power dissipation, and the reverse turbine regions of operation. Under normal operating conditions the ram effect on the projectile nose assures high positive suction pressure and eliminates the possibility of cavitation. Thus, in this series of tests, cavitation studies were not made.
