Question

Water is flowing through a tube. The water speed is 6.30 m/s at
point 1. Point 2 is 7.1 m higher than point 1. The diameter of the
pipe is 0.40 m at point 1 and 0.20 m at point 2. What is the
pressure *difference* P_{1}-P_{2} between
points 1 and 2? (ρ(H_{2}O)=1000 kg/m^{3})

Hi friend if you have any doubts leave a comment.. THANKS

Water is flowing at the rate of 1.676 m/s in a 3.068 inches’
diameter horizontal pipe at a pressure p1 of 68.9 kPa. It then
passes to a pipe having an inside diameter of 2.067 inch. The
density of the water is 998 kg/m3 . a) Calculate the new pressure
p2 in the 2.067inch pipe. Assume no friction losses b) If
the piping is vertical and the flow is upward, calculate the new
pressure p2. The pressure tap for p2...

A Venturi tube may be used as a fluid flow meter. If the fluid
flow rate in m3/s is 2.2 * 10-3 and the radius R1 = 2.4 *10-2 m of
the inlet tube is 2.1 times the radius R2 of the outlet tube, and
the fluid is water (ρ = 1000 kg/m3).
