Question

A horizontal pipe line carries water in a streamline flow. At a point along the pipe where the cross-section area is 10 cm2, the water velocity is 1 m/s and the pressure is 2000 Pa. What is the pressure of water at another point where the cross-section area is 5 cm2?

Solution

Correct option is

500 Pa

According to continuity equation,

        

Now according to Bernoulli's equation, 

     

     

which on solution gives  p2 = 500 Pa.
