MHT CET 2023 Physics question

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

(A)velocity is maximum and pressure is minimumCorrect
(B)pressure is maximum and velocity is minimum
(C)both pressure and velocity are minimum
(D)both pressure and velocity are maximum

Answer: (A)

Solution

By the equation of continuity, , so the velocity is largest where the cross-section is smallest, i.e. at the narrowest part. By Bernoulli's theorem for a horizontal pipe, , so where the velocity is maximum the pressure must
