There is a sudden increase in the diameter of a pipe from d₁
to d₂. What would be the ratio d₂
/d₁
if the minor loss is independent of the direction of flow? Assume coefficient of contraction C_c
= 0.6.

For a constant specific energy of 2 m., what maximum flow may occur in a rectangular channel 3 m wide?
