area of crosssection

A 200 mm long down sprue has an area of crosssection of 650 mm2 where the pouring basin meets thedown sprue (i.e. at the beginning of the down sprue).A constant head of molten metal is maintained by thepouring basin. The Molten metal flow rate is 6.5 × 105mm3/s. Considering the end of down sprue to be opento atmosphere and an acceleration due to gravity of104mm/s2, the area of the down sprue in mm2 at its end(avoiding aspiration effect) should be(a)650.0 (b)350.0 (c)290.7 (d)190.0
