Aliquid of density 1230 kg/m3 flows steadily through a pipe of varying diameter and height. at location 1 along the pipe, the flow speed is 9.39 m/s and the pipe diameter d1 is 11.5 cm. at location 2, the pipe diameter d2 is 15.3 cm. at location 1, the pipe is δy=9.59 m higher than it is at location 2. ignoring viscosity, calculate the difference δp between the fluid pressure at location 2 and the fluid pressure at location 1.

To develop this problem it is necessary to use the continuity equations and Bernoullie's theorem.

It is known from Bernoullie's theorem that

Where

P = Pressure

g = Gravity

h= Height

v = Velocity

= Density

On the other hand we have that the continuity equation is given by

Where A is the Cross-sectional area and v the velocity.

For our values we know that

Using Bernoulli's expression we can now find the pressure difference,
