Question

Water with a density of 998 kg/m3 enters a 50 mm pipe fitting horizontally, as shown in
figure, at a steady state velocity of 1 m/s and a gauge pressure of 100 kN/m2. It leaves the
fitting horizontally, at the same direction, at an angle 45° with the entrance direction. The
diameter at the outlet is 20 mm. Assuming the fluid density is constant, the kinetic energy
and momentum correction factors are unity and the friction loss in the fitting is negligible,
calculate
(i) the gauge pressure at the exit of the fitting
(ii) the forces in the x and y directions exerted by the fitting on the fluid

Answer 1

Answer:

Water with a density of 998 kg/m3, enters a 50 mm pipe fitting horizontally at a steady velocity of 1m/s and a gauge pressure of 100 N/m2. It leaves the fitting horizontally, at the same elevationat an angle of 45° with the entrance direction. Diameter at outlet is 20 mm, Assuming the fluid density is constant, kinetic energy and momentum correction factors are exist and unity. Friction loss in the fitting is negligible. Calculate gauge pressure at the exit of the fitting.
