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

  1. Achanging continuously with time
  2. Bgreater at M than at N
  3. Cgreater at N than at M
  4. 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 .
