Question

A broad pipe having a radius 10 cm branches
into two pipes of radii. 5cm and 3cm. If the
velocity of flowing water in the pipe of radius
3cm be 5 cm/s. Determine the velocities of water
in the remaining two pipes. Given that the rate
of discharge through the main branch, is 600
cm/s.
1 V1 = 6 cm/s and v2 = 22.2 cm/s
2) V1 = 4 cm/s and v2 = 12.2 cm/s
3) v1 = 3 cm/s and v2 = 12.2 cm/s
4) None of these
​

Answer 1

Answer:

option 3: v1=3cm/& V2= 12

w cm/s

Answer 2

Explanation:

as A1v1=A2v2+A3v3 so we can now calulate the A1, A2 & A3 with the radius given (10,5&3) cm respectively

Q=600π and v3= 5cm/s so we put the values of these and on comparing with this Q we shall get the v1&v2 as 6cm/s and 22.2cm/s.
