Extracted text: A 200 mm long downsprue has an area of cross section of 650 mm where the pouring basin meets the downspure. A constant head of molten metal is maintained by the pouring basin. The molten metal flowrate is 6.5 × 10’ mm’/s.Considering the end of the down sprue to be open to atmosphere and acceleration due to gravity as 10' mm/s² at it ends,find the area of thesprue at the end.
