Water flow a rate of 0.5 m3
/s rising through a 50 o
contracting pipe bend. The
diameter at the bend entrance is 700 mm and at the exit 500 mm as
shown in Figure
1. If the pressure at the entrance to the bend is 200 kN/m2
, determine the
magnitude and direction of the force exerted by the fluid on the
bend. The exit
entrance of the bend is 0.4 m higher than the entrance and the bend
has a volume of
0.2 m3
. Neglect the friction losses.
