Fluid Mechanics in SWCE

In a venturimeter, the angle of divergence in the diffuser cone is kept very small ($5^\circ$ to $7^\circ$) compared to the convergent cone ($20^\circ$ to $22^\circ$) to:

Options:

• (A) Prevent flow separation and large eddy formation, thereby minimizing head loss
• (B) Increase cavitation
• (C) Reduce manufacturing costs
• (D) Increase water velocity in the diffuser
