Im on Section 7 Fluids, page 74. The book begins talking about Bernoulli's equation (7.35)
http://hyperphysics.phy-astr.gsu.edu/hbase/pber.html here's link for said equation.
However, they begin to talk about an "easier, more user friendly" version of the equation , which is
k = P + 1/2pv^2 +pgh
P= pressure against inner walls
p= density
v= velocity
g=gravity constant
h= height
But there do not elaborate more than that on it (so much for user friendliness). I am confused for two reasons,
1. I have no clue what k means (k for constant?)
2. Other than it being smaller, why is it "more useful" in this form?
