I think fluids travel faster near the center of pipes and tubes better than at the edges because they are able to travel much faster, and smoother in the center rather than the edges because the fluids have to turn, which could cause the rest of the incoming fluids to stop, which would make it much slower when traveling through the edges than through the center.
B. Sonar I had the same question what a coincidence but I had a book about it so here's your answer
-- The theory of gravity gives a good explanation for things
that we see happening.
-- The theory of gravity predicts things that turn out to be true
when we test them.
-- Nobody has come up with a different theory that explains things better
and makes more accurate predictions that the theory of gravity does.
-- The theory of gravity can't be proved.
Answer:
Properties of semiconductors are determined by the energy gap between valence and conduction bands. To understand, what is semiconductor, we have to define these terms. In solid-state physics, the energy gap or the band gap is an energy range between valence band and conduction band where electron states are forbidden.
Answer:
Explanation:
given,
diameter of inlet = 11.2 cm
r₁ = 5.6 cm
r₁ = 0.056 m ∵ 1 cm = 0.01 m
speed of inlet = 5 m/s
diameter of outlet = 17.5 cm
r₂ = 8.75 cm
r₂ = 0.0875 m ∵ 1 cm = 0.01 m
speed of outlet = ?
using continuity equation
A₁ v₁ = A₂ v₂
π r₁² v₁ = π r₂² v₂
Velocity of liquid at the outlet of the tube is equal to 3.2 m/s
