ure 17 are plotted values of - against - for different assumed values of By plot- c c c ting these dimensionless quantities instead of the simple quantities p, y, and s, the plot can be used for diaphragms of all sizes. Case 2. x>c (See fig. 1(3, B). This case is characterized by the facts that the… … Vdlc Fig. 17.—Curves for use in comput ing effective areas of slack diaphragms. Case I From Figure 18 the following equations are obtained: (11) r a =-s-\- p 2r' sin i/^a'= V(c + p)'4-?/'2 (12) (13) ?/' = (c + p) tan fi' = {c-^p) tan 1/2 a' The primes are used to signify Case II.
