Extract

A low speed wind tunnel was needed for work by Dr. J. Juillet at the Belleville Institute to determine the number and direction of insect flights in a given time at different wind speeds and hence to determine the influence of wind on flight activity. This paper describes a tunnel designed to produce wind speeds of up to 9 miles per hour with uniformity within ± 5 per cent.
