✦ Synopsis

Furthermore, von Karman and Tsien (1938) found the formula (LJ = (2J" in "closer agreement with experimental data". More recently, Svoboda and Hartman (1981) and Hartman and Svoboda (1986) have used the following formula in fluidization studies. Il 1.81 x 1O-5 (10) Thus, if either eq. (8) or (9), due respectively to von Karman and Tsien (1938), and Lord Rayleigh, were used for deriving eq. (5), the predicted value of d[ given in eq. (5) would essentially be in exact agreement with the experimental results of Fan et al. (1986) which were represented by Q = -1.73. This indicates that n is independent of temperature, in contrary to the suggestions of Fan et al. (1986), and that the experimental results are much more accurate than was previously thought.
