Problem A6: An incompressible fluid of density ρ is flowing from left to right through the tubes shown below. The speed entering on the left is v₀, and the diameter on the left is n₁. The diameter on the right is n₂. If the difference in pressure from the left to the right side is Δ P = P₁ - P₂ = n₃ ρ v₀²/2, what is n₃? Note that n₁ and n₂ have the same units of length, and that n₃ is unitless.

n1 =	n2 =	Input n3:
