Problem (11): A pipe discharges an unknown fluid into the atmosphere from a tank of depth (h) through a pipe of length (L), and diameter (d). Given the values of L [m], d [cm], and (h) [cm], calculate the discharge rate (Q) [lit/s] that would maintain Laminar flow in the pipe with a Reynolds number of Re-1500. Ignore minor losses. Givens: L = 139.364 m d = 12.614 cm h = 76.609 cm Answers: ( 1 ) 6.911 lit/s (2) 8.179 lit/s ( 3 ) 4.244 lit/s (4) 4.987 lit/s h d
