An ideal incompressible fluid flows at 12 m/s in a horizontal pipe. If the pipe widens to twice its original radius, what is the
grandymaker [24]

Answer:

d) 3 m/s

Explanation:

As we know by equation of continuity

A_1v_1 = A_2v_2

here we have

A_1 = \pi r^2

A_2 = \pi (2r)^2

A_2 = 4\pi r^2

now from above equation we have

\pi r^2 v_1 = 4\pi r^2 v_2

v_2 = \frac{v_1}{4}

here we have

v_1 = 12 m/s

v_2 = 3 m/s
