A pressure die casting setup was tested by injecting water (density 1000 kg/m3) at a pressure of 200 bar. Mould-filling time was found to be 0.05 s. Afterwards, the actual casting is made by injecting the liquid metal (density 2000 kg/m3) at an injection pressure of 400 bar. Neglect all losses (friction, viscous-effect, etc.). The approximate mould-filling time (in s) is: |
A. | 0.05 |
B. | 0.075 |
C. | 0.1 |
D. | 0.2 |
Answer» B. 0.075 | |
