The ögure shows a piping system. water áows upward and to the right (from a to b) in the 4-inch-diameter pipe. the pipe exits to the atmosphere at b. there is a clamp at point a that holds the pipe in place. point b is 10 feet above and 10 feet to the right of point a. note that patm = 2116 lb/ft2 and h2o = 1: 94 slugs/ft3 . figure for problem 5. (a) a meter at point a reads va = 20 ft/s. find the velocity at b and the pressure at a if viscous e§ects can be neglected. (b) for the same meter reading as in (a), önd the velodity at b and the pressure at a if viscous e§ects cannot be neglected. (you may approximate pipe lengths based on the information given.) the pipe is galvanized iron with a standard roughness height of 0.0005 ft. (c) find the reaction force due to the water áow at the clamp at point a assuming there is no other support for the pipe. use the partial results from (b) to önd the force. (you may neglect the weight of the pipe.)
