Water is flowing in a horizontal tube. The pressure at a point is 0.01 m of Hg at which the velocity is 0.6 m/s. What is the pressure at a point where the velocity is 0.8 m/s ?
According to the Bernoulli's equation,
P1 + ρ1gh1 + ½ ρ1 V1^2 = P2 + ρ2gh2 + ½ ρ2 ...
The solution gives the principle involved behind the problem with a step by step procedure to solve it.
