HM 220

Airflow Study Unit

Technical Description

The system comprises 2 components that are connected together for the experiments. A fan draws air through a section of pipe. The air flow rate can be measured with various measuring inserts such as a nozzle/orifice, Pitot tube or iris diaphragm. The measuring inserts are connected to a multiple tube manometer using hoses; the pressure differences can then be read on the manometer. Measuring glands are also fitted to the pipe section at evenly spaced intervals; these can be used for determining pipe friction, pressure losses or velocity profiles. The tube manometer can be tilted to increase precision and can be fixed in various positions. Open jet experiments can be performed at the fan outlet.
