(a) Find the speed v2 of the gas in the larger original pipe.

(b) Find the volume flow rate Q of the gas.

anything would help. i have asked everyone and they dont know either.

**Anon**, Monday, December 2, 2013 at 8:45pmTry to use P2-P1 = ρ/2(v1^2-v2^2)

Derived from P1 + 1/2ρv1^2 = P2 + 1/2ρv2^2

Then A1V1 = A2V2 is from continuity and can be expressed V1 = A2V2/A1

You get the equation P2 - P1 = ρ/2((A2V2/A1)^2 - V2^2) via substitution

And then simplify to 2(P2-P1)/ρ = A2V2/A1 - V2^2

Plug in and solve
