GATE MT 2020 Q19. In a top gated mold, liquid metal enters the mold cavity as a freely falling stream under gravity from a height of 0.5 m. Ignore the fluid friction due to viscosity and the drag due to change in the direction of flow. If the volume of the mold cavity is 10m^3, then the time required to fill the mold is ________s (round off to nearest integer). Given : 1. Acceleration due to gravity is 9.8 ms^-2 2.Cross – sectional area of gate is 0.2 m^2.
