Subject: how do i calculate pressures from flow velocities?

Hi,

I'm working on a model to simulate fish feeding under water by suction. I 
calculate velocities along the central axis of the fish by calculating the 
volume rate change (which I measure throughout the feeding cycle) divided by 
the frontal area along the lenght of the fish. I end up with velocity changes 
in time and in space in the buccal cavity. What I want to do next is calculate 
pressures from these velocities, but here's where I get stuck. Any help will be 
greatly appreciated!
