For Gating system of casting, choke area (A) may be written as [where, m = mass of casting, ρ = density of molten metal, H = effective metal height, C = efficiency factor, t = pouring time]:

Question

TuteeHUB · Accepted Answer

$A = \frac{{tm}}{{\rho C\sqrt {2gH} }}$

TuteeHUB · Answer

$A = \frac{m}{{\rho tC\sqrt {2gH} }}$

TuteeHUB · Answer

$A = \frac{{m\sqrt {2gH} }}{{\rho tC}}$

TuteeHUB · Answer

$A = \frac{{\rho m}}{{tC\sqrt {2gH} }}$

1.	For Gating system of casting, choke area (A) may be written as [where, m = mass of casting, ρ = density of molten metal, H = effective metal height, C = efficiency factor, t = pouring time]:
A.	\(A = \frac{m}{{\rho tC\sqrt {2gH} }}\)
B.	\(A = \frac{{tm}}{{\rho C\sqrt {2gH} }}\)
C.	\(A = \frac{{m\sqrt {2gH} }}{{\rho tC}}\)
D.	\(A = \frac{{\rho m}}{{tC\sqrt {2gH} }}\)
Answer» B. \(A = \frac{{tm}}{{\rho C\sqrt {2gH} }}\)
