Question

A horizontal pipe line carries water in stream line flow . At a point where the cross sectional area is 10 cm^2 the water velocity is 1 ms and pressure is 2000 pa . The pressure of water at another point where the cross sectional area is 5cm ^2 , is
.​

Answer 1

Answer:

Hey Buddy,

Let's Start solving:-

By observing the question, By Taking continuity equation,

A1.v1 = A2.v2

Which gives v2 = 10/5 x 1 = 2 m/s.

Now,

$ρ1 + 1/2ρ(v1 {)}^{2} = ρ2 + 1/2ρ(v2 {)}^{2}$

$2000 + \frac{1}{2} \times 10 {}^{3} \times 1 {}^{2} = ρ2 + \frac{1}{2} \times 10 {}^{3} \times 2 {}^{2}$

Therefore, We finally get ρ2 = 500 Pa.

Pressure of water at another point is 500 Pascals.

Hope it helps : )
