Alyssa Owen · Answer 1

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
