Question

The length of the divergent portion of Venturimeter in comparison to convergent portion is

• A. Less
• B. More
• C. Same
• D. More or less depending on capacity

Answer 1

Answer:

B. More

The length of the divergent portion in a venturimeter is more than that of convergent portion to avoid every loss due to separation. Bernoull's theorem and theid energy continuity are used to measure the rate of flow of a fluid through the device. The angle of divergence should not exceed 7° to prevent flow separation.
