A pressure die casting set-up was tested by injecting water (density 1000 kg/m
) at a pressure of 200 bar. Mould-filling time was found to be 0.05 s. Afterward, the actual casting is made by injecting the liquid metal (density 2000 kg/m
) at an injection pressure of 400 bar. Neglect all losses (friction, viscous-effect, etc.). The approximate mould-filling time (in s) isYour answerChoose one option.
