Summary:

In laying out apparatus for the laboratory testing of superchargers for aircraft engines at the Langley Memorial Aeronautical Laboratory, it was found most convenient to measure the air on the inlet side by drawing the air from the atmosphere through thin plate orifices at low velocities into a box and thence through a throttle into a large reservoir which in turn was in free communication with the supercharger. The orifice coefficients for this condition were unknown, as the desired type of orifice had been calibrated with the flow from the box into the atmosphere, instead of the reverse direction which would obtain with this apparatus. The present experiments were therefore undertaken in order to obtain information regarding the relationship between the coefficients for flow in the two directions.
