✦ Synopsis

In our test at a heat flux of 25,000 B.Th.U./(hr)(ft)z, types 1 and 4 flow averaged 1.05 cm/set while type 2 flow averaged in the atmosphere. Kappears to us the analogy should be 0.3 cm/set. quite complete up to the point of cloud formation in the Transient dynamic effects due to the necessity of establish-atmosphere where, of course, transfer of the latent heat of ing flow where no flow existed were short-lived and in no case vaporization to clouds makes the analogy break down.

were visible more than 0.8 set after the strip was suddenly heated.

There is also an apparent close similarity between the
