Hi all,(adsbygoogle = window.adsbygoogle || []).push({});

If I only know the Pressure given by a known Force on the barrel side of the syringe, the Density of the fluid, the Cross Section Area of the two parts of the syringe, the length of the syringe barrel and a ball with known Mass being pushed by the fluid flowing out of the syringe. How to know if the flow is steady or not? And how to calculate the gain in kinetic energy of the ball after the syringe is pushed to limit by the constant force?

Thx
