Given, horizontal tube of variable diameter By using equation of continuity
Av = constant ...(i)
where, A is area of cross-section and v is velocity of fluid through that cross-section.
As, p=

F

A

⇒A=

F

p

Substituting in Eq. (i), we get

F

p

.v= constant
If force is same.
∴

v

p

= constant
If pressure is least, then velocity is highest.
