![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.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fe009f1ae-c2b7-4c8f-8a9a-a452e6507b67%2Fb9f40cd7-a2ab-40e6-bec5-95f4e1bef179%2Fgbh5lio_processed.jpeg&w=3840&q=75)
