## Main Question or Discussion Point

I am familiar with the idea of pump head and system pressure losses, pump curves etc.

However, a friend was asking about the relationship between static pressure, force and acceleration.

For example, if the pump supplies a certain pressure (P) at a given flow rate, is there not a force which corresponds to that pressure (similar to P=F/A). The problem is, that if there is a constant force being applied, that would imply a constant acceleration. In reality, most systems have a constant velocity.

I know the logic is wrong, but I am having trouble explaining why, or pinpointing the reason.

Thanks for your help! :thumbs:
