✦ Synopsis

iments (~4.5), the Wyngaard calculation gives an attenuation of 8%. Since our experimental results have a scatter of + 8%, it is not possible to see this theoretical trend in our data. F o r Azad and Kassab's (1989) data, in which lJLK varies from 8 to 35, Wyngaard's calculations indicate an attenuation of the order of 22% to 65%. It should also be noted that Azad and Kassab's extrapolation of their data to "zero-wire-length" does not take into account the flattening out that occurs in the Wyngaard correction curve for lw/LK less than about 5.

The isotropic dissipations obtained in these experiments agree very well with those obtained by Browne et al. (1987). However, they are well below the actual dissipations reported by those authors.
