Question
Water is discharged steadily from a tank to the atmosphere through a commercial steel pipe
(roughness e = 0.046 mm). The pressure (gauge) on the top of tank is 1 bar. Assume the water
level 5 m in the tank remains unchanged. The flowrate is 0.1 m³/min and the pipe has a diameter
of 5 cm. The loss coefficient due to contraction from the tank to the pipe is 0.5.
(a) Determine the pipe length (when the angle = 30°).
(b) If the pipe is horizontal (i.e., the angle = 0), how long will the pipe be?
p = 1 bar
(gauge)
