Wind Tunnel flow simulations

My guess is this is some sort of a homework question. The first requirement is a knowledge of Bernoulli's equation and how to apply this to the flow of fluids, in this case, air. This simulation has using been performed using tools found in Solid works. I think the first thing to do would be to compare the simulation to results obtained Bernoulli's equation, then read the questions thoroughly and see how you go at answering them.

The key to becoming good at these type of simulations is an understanding the theory behind them. To get good results you need to understand exactly what you are simulating, supply the required data correctly and if you understand exactly what is happening if your results are believable.
