The elbow for a 5-in-diameter buried pipe is subjected to a static pressure of 10 lb/in². The speed of the Water passing through it is v = 8 ft/s. Assuming the pipe connections at A and B do not offer any vertical force resistance on the elbow, determine the resultant vertical force F that the soil must then exert on the elbow in order to hold it in equilibrium. Neglect the weight of the elbow and the water within it.
