In a metal casting process, molten copper alloy is poured into a sand mould. The level of molten metal in the pouring basin is at a height of 300 mm from the runner having diameter of 10 mm. if the density and melting temperature of molten copper alloy are 9000 kg/m3 and 10000C, respectively then the rate of flow of molten metal into the mould neglecting friction and other losses, in cm3/s is _____________
