Water flows steadily through a horizontal pipe of variable cross-section. If the pressure of water is `p` at a point where the velocity of flow is `v`, at another point (pressure `p'`), where the velocity of flow in `etav` : The following statements are given below

Options

A. `(p')/(p) lt 1`, when `eta lt 1`
B. `(p')/(p) lt 1`, when `eta gt 1`
C. `(p')/(p) gt 1`, when `eta lt 1`
D. `(p')/(p) gt 1`, when `eta gt 1`

Explanation

`eta gt 1`, velocity at another point will be greater then `v`
so, pressure `(p') lt p`
`eta lt 1`, velocity at another point will be less then `v`
so, pressure `(p') gt p`
