Question

A non-viscous incompressible liquid is flowing through a horizontal pipe of constant cross section. Bernoulli’s equation and the equation of continuity predict that the drop in pressure along the pipe: 

A. is zero 

B. depends on the length of the pipe 

C. depends on the fluid velocity 

D. depends on the cross-sectional area of the pipe 

E. depends on the height of the pipe

Comments

Due to continuity equation, for constant A : Velocity is constant
and there is no change in potential energy
So due to Bernoulli's equation,the pressure is constant and the change in pressure equals zero

Answer 1

A .   is   zero
