G factor in centrifugal casting
WebMar 2, 2024 · G-factor is the ratio of centrifugal force to weight: \(G =\frac{F_c}{mg} = \frac{mr\omega^2}{mg}\) Calculation: Given: G-factor = 70, d o = 25 cm = 0.25 m, g = 10 … WebMechanical Engineering questions and answers. True centrifugal casting operation is performed horizontally to make large diameter copper tube sections. The tubes have a length = 1.0 m, diameter = 0.30 m, and wall thickness = 15 mm. If the rotational speed of the pipe = 700 rev/min, (a) determine the G-factor on the molten metal.

Here, ‘GF’ is the G-factor of the centrifugal casting method to be applied. It is calculated as centrifugal force divided by weight. GF is an empirical value and if it is very low, the molten metal inside the mold cavity will not remain stuck to the walls of a mold, and it will ‘rain’ inside the mold.
