Question

When the speed of water in 4 inch square pipe is 10ft. The speed of water in 2 inch square pipe will be ​

Answer 1

Answer:

it would be 40

hope it helps

plese mark me as the brainliest

Explanation:

Answer 2

Answer:

40 Feet per second !

using Continuity Equation volume Flow rate should be Same, assuming

a. incompressbility hence Density is Constant.

b. constant head for a leveled pipe

now we equate flow rate A1xV1= A2xV2

v2/v1 = Square of(D1/D2)= 4

V2 = 4x10= 40 feet per second
