Water is flowing through a horizontal pipe in stream line flow. At the narrowest part of the pipe

Step-by-step solution

Using equation of continuity, A ₁ ~V ₁= A ₂ ~V ₂ In streamlined flow, as the product of Av is a constant, the velocity at the narrowest part will be maximum. By using Bernoulli's principle, P + 1 2 v^2+ g h= Constant We see that g h is constant because the pipe is horizontal. As velocity increases, for the equation to remain constant, P has to decrease. Velocity will be maximum and pressure is minimum
