EFC2/T22.3.17. Contd.

In this connection we attach to Mr. Royce's copy of this note a photostat copy of an article taken from the Auto-Car of May 8th 1915, which we think may be of interest.

The limiting flow of 13 cubic feet per min. shown by the graph on p.504 agrees well with the result for this flow calculated from Fliegner's formula, see X.2907. C/O.{Mr Oldham} flow of gases through orifices.
