True centrifugal casting is performed horizontally to make copper tube sections The tubes have a length 1.0 m, diameter 0.25 m, and wall thickness = 15 mm. (a) If the rotational speed of the pipe= 700 rev/min, determine the G-factor on the molten metal.

Respuesta :

Answer:

the G factor on the molten metal is 68.53

Explanation:

G factor = \dfrac{R(\dfrac{\pi N}{30})^2}{g}

given,

  diameter = 0.25 m

  radius     = 0.25/2  = 0.125 m

N = 700 rev / min

now by substituting value in the formula

G factor = \dfrac{R(\dfrac{\pi N}{30})^2}{g}                

             = \dfrac{0.125(\dfrac{\pi \times 700}{30})^2}{9.8}

             = 68.53

hence, the G factor on the molten metal is 68.53
