Problem 5
Water is flown at a constant rate through a circular pipe divided into three sections by two identical
bends. The pressure head is measured at cross-sections A and B. The pressure head difference
between cross-sections A and B is Ah = 33 cm. The diameter of the pipe is d= 150 mm, the flow
velocity is v = 1.6 m/s. The friction coefficient is A = 0.02.
a/ What is the minor loss coefficient of the bends?
b./ Sketch the energy and pressure grade lines on the section between A and B without indicating the
values.
