Question

Ideal fluid flows along a flat tube of constant cross-section, located in a horizontal plane and bent as shown in figure above (top view). The flow is steady. Are the pressures of the fluid equal at points $1$ and $2$?

• A. Pressure at point $1$ is greater
  
• B. Pressure at point $2$ is greater
  
• C. Yes
• D. Pressure at both the points is zero
  

Answer 1

The correct option is A Pressure at point $1$ is greater

It is to be remembered that pressure in a liquid at any point on the same level are always equal & increases with depth.

It is defined $P=\rho gh$

So with the increase in depth pressure increases.
