1. A mold sprue is 20 cm tall (distance between point 0 and point 2 in the drawing below) and the cross-sectional area at its base is 2.5 cm². The sprue feeds a horizontal runner leading into a mold cavity whose volume is 1560 cm³. ▪ What is the velocity of the molten metal at the base of the sprue? ▪ What is the volume rate of flow in the sprue? ■ What is the time to fill the mold TMF?
