It's about how to measure an increase in wind velocity through a restriction.It starts with an area that is 17' wide by 14' high by 20' deep and it's a right triangle with a 16 degree slope. I need to know the increase in wind velocity that would occur if there were a 25mph wind and a 35 mph wind going through this right triangle from the base and through a 10'' opening in the top, that's 10'' by 17' So it starts at 17' by 14' and ends up 10'' by 17',what is wind speed at the opening?
