IDEAL DISCHARGE OF NOZZLES (a).

Q = A √2 gh
c.ft/sec. = sq. ft. x ft/sec.

q = 30.48³ x 60 x a/144 √64.38 h.{Arthur M. Hanbury - Head Complaints} cc./min.

= (30.48³ x 60 x √64.38)/144 x .7854 d² √h.{Arthur M. Hanbury - Head Complaints} cc/min.

= 74350 d² √h.{Arthur M. Hanbury - Head Complaints}


d = .046875
3/64 = .09375
3/32 = .125"
1/8 = .1875"
