Question 866195: water is moving with a speed of 5 m/s through a pip with a cross-sectional area of 4cm^2 . the water gradual descends 10 m as the pipe cross-sectional area increases 8cm^2 . if the pressure at the upper level is 1.5*10^5 , the pressure at the lower level is ?

That's not really an algebra problem.
I'm assuming pressure is in Pa.
I assume it's 1D incompressible Bernoulli flow.

From conservation of mass,
A%5B1%5D%2AV%5B1%5D=A%5B2%5D%2AV%5B2%5D
V%5B2%5D=5%284%2F8%29=2.5m%2Fs
.
.

p%5B2%5D=257375Pa
