Figure P5.46 shows a lateral pipe fitting. This particular

fitting has a mainline diameter of 4.0 in. The diameter of the

lateral is 3.0 in., and the lateral angle is 45°; 60 °F water is flowing in the lateral. Measurements show that the pressure at point

1 is 34.0 psig, the pressure at point 2 is 35.0 psig, the pressure

at point 3 is 33.5 psig, and the flow rate at point 2 is 1.0 ft3/s.

Determine the horizontal and vertical force components (Fx and

Fy) required to hold the lateral fitting stationary. Neglect gravity.

Q1 = 1.63 ft3/s.
