Horizontal tube of non-uniform corss-section has radii of 0.1 ~m and 0.05 ~m respectively at M and N. For a streamline flow of liquid the rate of liquid flow is
Options
- Achanging continuously with time
- Bgreater at M than at N
- Cgreater at N than at M
- Dsame at M and N
Correct answer
C. greater at N than at M
Step-by-step solution
The velocity of flow will increase if cross-section decreases and vice-versa. aligned ie, & A ₁ v ₁ &= A ₂ v ₂ or & Av &= constant aligned Therefore, the rate of liquid flow will be greater at N than at M .
