Consider a flow of water being directed through a flanged joint, as shown in the figure below. The velocity of the fluid at the joint inlet is 4.25 ft/s, and a static pressure gauge next to the inlet indicates a fluid gauge pressure of 2.28 psig. The joint redirects the fluid by 30°, and decreases the diameter of the water pipe from 12.5 in to 6.25 in. 

Determine the horizontal force in the flanged joint, and be sure to indicate direction (tension or compression) (lb_f).
