I have this problem:(adsbygoogle = window.adsbygoogle || []).push({});

Water flowing in a horizontal pipe is at a pressure of 1.5 105 Pa at a point where its cross-sectional area is 1.50 m2. When the pipe narrows to 0.400 m2, the pressure drops to 1.16 105 Pa.

(a) Find the water's speed in the wider pipe

(b) Find the water's speed in the narrower pipe.

I tried using Bernoulli's Principle but I can't get it.

I took the (p)(g)(h) out of both sides since the pipe's height doesn't change. And then I tried solving for v1 and v2 but there are two unknowns and I don't know what to do after that....

If anyone could help, that would be awesome.

Thanks in advance.
