Compute the discharge of water through 75 mm pipe if the mean velocity is 2.5 m/sec.
The discharge of air through a 600-mm pipe is 4 m3/sec. Compute the mean velocity in m/sec.
A pipe line consists of successive lengths of 380-mm, 300-mm, and 250-mm pipe. With a continuous flow through the line of 250 Lit/sec of water, compute the mean velocity in each size of pipe.
