True centrifugal casting process in horizontal configuration is to be used for casting a metallic cylinder with outside diameter 0.275 m and inside diameter 0.250 m
Q. True centrifugal casting process in horizontal configuration is to be used for casting a metallic cylinder with outside diameter 0.275 m and inside diameter 0.250 m. If G-factor (ratio of centrifugal force experienced by the rotating cast metal to its weight) is 65 and acceleration due to gravity is 9.8 m/s2, the minimum rotational speed (in rpm) required is closest to
Ans: 650
Sol:
In true centrifugal casting process, the G-factor (GF) is defined as the ratio of centrifugal force experienced by the rotating cast metal to its weight.
