I am using distance vs volume of water. Of course, the volume of water is my independent variable. What equation should I use for this lab?

**MathMate**, Tuesday, August 31, 2010 at 9:09amAccording to a Wiki article, the formula for the instantaneous thrust is

F=2PA_{t}

where

F=thrust

P=pressure

A_{t}=area of the nozzle

Obviously the mass changes with time as well as the pressure. So both F, mass and P are functions of time, and you will need to integrate the resulting acceleration over time to get the distance.

Do read through the safety precautions before attempting this lab.
