I am building a small wind tunnel, and I have a few questions about it.
First: The Fan I am using produces 800cfm and is 12'' in diameter, I am going to narrow it down to 6''. The calculated wind speed that I got was 74.5km/h. Can anyone back me up on this?
Second: When I use scale models of say wing foils or other things of that nature should the wind speed in the tunnel be higher or lower then in a full scale test. And can anyone point me in the direction of any equations to find these values?
Third: What is a cost effective smoke device?
