A sprue in a sand mould has a top diameter of 20 mm and height of 200 mm. The velocity of the molten meal at the entry of the sprue is 0.5 m/s. Assume acceleration due to gravity as 9.8 m/s 2 and neglect all losses. If the mould is well ventilated, the velocity (upto 3 decimal points accuracy) of the molten metal at the bottom of the sprue is________m/s.

A sprue in a sand mould has a top diameter of 20 mm and height of 200 mm. The velocity of the molten meal at the entry of the sprue is 0.5 m/s. Assume acceleration due to gravity as 9.8 m/s² and neglect all losses. If the mould is well ventilated, the velocity (upto 3 decimal points accuracy) of the molten metal at the bottom of the sprue is________m/s.
