Question
LAB 5. THANK YOU HYDRAULICS LABORATORY
Is there a significant difference between the discharge coefficient derived from the experiment
with that of coefficient of discharge from Francis formula? Discuss the possible reason for such
discrepancy.
1.
A rectangular sharp-crested weir with end contractions is 1.5 m long. How high should it be
placed in a channel to maintain an upstream depth of 2.25 m for 0.45 m³/s flow? Use Francis
formula.
2.
3.
Solve problem no. 2, using the general weir formula and the average experimental coefficient of
discharge, Ca.
