How Does Water Pressure Affect the Initial Velocity in Projectile Motion?

[mod note: post moved into homework forum, so template is absent]

G'day,

I have an open ended investigation to do for school, and was wanting to do an experiment involving the motion of water from a hose, as this would give me a good parabolic curve to view. I wish to examine two independent variables. First one is angle of launch - pretty easy. I'm having trouble with a second one through.

I was wondering whether i could change the pressure of the actual tap/ hose, and whether or not this has any correlation to initial velocity, as in can I work out the initial velocity if I measure the pressure of the tap using a pressure gauge, for example.

Any help on the topic would be much appreciated. Cheers.

Hi Bucko.

Sure, the more water that passes through the hose per second, the faster its velocity. So the problem becomes: how to calculate or measure that exit velocity.

Any ideas?
