At one point in a pipeline the water’s speed is 3.00 m/s and the gauge pressure is $5.00\times {10}^{4}Pa$ . Find the gauge pressure at a second point in the line, 11.0 m lower than the first, if the pipe diameter at the second point is twice that at the first.

You can still ask an expert for help

Step 1

The diameters of the two pipe cross-sections are

Step 2

Let's first determine the relation between the velocities based on the continuity equation

Step 3

Since the atmospheric pressures are the same we can write Bernoulli's equation as

Step 4

At this point we can insert all the given values to get the following

Show that the graph of an equation of the form

$A{x}^{2}+C{y}^{2}+Dx+Ey+F=0,A\ne 0,C\ne 0$

where A and C are of opposite sign,

(a) is a hyperbola if$\frac{{D}^{2}}{4A}+\frac{{E}^{2}}{4C}-F\ne 0$
