Question: The fi re hydrant is tested under a high standpipe pressure. The total flow of 10 ft 3 /sec is divided equally between the two

The fi re hydrant is tested under a high standpipe pressure. The total flow of 10 ft³/sec is divided equally between the two outlets, each of which has a cross-sectional area of 0.040 ft². The inlet cross-sectional area at the base is 0.75 ft². Neglect the weight of the hydrant and water within it and compute the tension T, the shear V, and the bending moment M in the base of the standpipe at B. The specific weight of water is 62.4 lb/ft³. The static pressure of the water as it enters the base at B is 120 lb/in.²
