Question

A fluid is in streamline flow across a horizontal pipe of variable area of cross section. For this which of the following statements is correct?\

Professor PC Thomas Classes · Answer

(a) : According to equation of continuity,\ $A v=$ constant\ Therefore, velocity is maximum at the narrowest part and minimum at the widest part of the pipe.\ According to Bernoulli's theorem for a horizontal pipe, 
$ P+\frac{1}{2} ho v^{2}=	ext { constant } $ 
Hence, when a fluid flow across a horizontal pipe of variable area of cross-section its velocity is maximum and pressure is minimum at the narrowest part and vice versa.\
