    There is a sloped metal tube of X inches wide that runs Y feet at a Z degree angle. At the top it is connected to a reservoir, and at the bottom it is open to the air after a stop valve. When the stop valve is closed (almost instantaneously) there will be an increase in pressure. I need to have you generate the pressure curve over time until the pressure is dissipated.
