Describes experimental techniques used in the low-speed wind tunnels at the Building Research Station when studying air flow around buildings and pressure distribution over their surfaces. Includes flow visualisation both in the stream and in boundary layers over surfaces, velocity measurements around small-scale models, and methods of building models containing pressure tappings. Gives names of suppliers and details of some instruments and equipments. Describes in an appendix how a simply constructed heated-sphere anemometer is made.
