In a stream line steady flow, two points A and B on a stream line are 1 m apart and the flow velocity varies uniformly from 2 m/s to 5 m/s. What is the acceleration of fluid at B?

Answer 1

Concept:

For flow along a stream line acceleration is given as

If V = f(s, t)

Then,

For steady flow

Then

Since V = f(s) only for steady flow therefore

Therefore

Calculation:

Given, V_A = 2 m/s, V_B = 5 m/s, and distance s = 1 m

So acceleration of fluid at B is
