Question: A casting is filled by a top gating system. The cross - sectional area of in - gate is 1 0 cm ^ 2 .

A casting is filled by a top gating system. The cross-sectional area of in-gate is 10 cm^2. The 5 dimensions of the mold cavity are 100 cm x 150 cm x 30 cm and the total height of the pouring basin and the sprue is 50 cm. Assume that the frictional loss during the flow of liquid metal is negligible. Calculate the mold filling time in seconds.
