Question #70d7b

Answer 1

see explanation

Explanation:

When water flows from pipe with diameter `d_1` and velocity `v_1` to the pipe with diameter `d_2` and velocity `v_2` and is valid that `d_1>d_2` then `v_1< v_2`

It comes from Continuity equation. Simplified form: `S_1*v_1=S_2*v_2`
where S means the area of a circle: `S=pi*r^2=pi*(d/2)^2`
