... metal density in the casting than would otherwise result. Figure 3 shows that a entrifugal casting mold spinning at a peripheral velocity of 305 m/min (1000 ft/min) at the outer diameter of the casting(s) will have an equivalent head of 9 m (30 ft). This is equivalent to a pressure of 703 kPa (102 psi...
