Problem Set 1) Munson 8.1.5 2) Mercury at 20 C flows through a 200 m long glass tube which is 1 cm in diameter. At end A, the elevation is 100 m and the pressure reads 150 kPa, and at the other end, the elevation is 20 m and the pressure reads 300 kPa. Calculate: a) the head loss b) the direction of flow. c) the flow rate 3) Munson 8.4.25 4) Munson 8.6.7 5) Munson 8.4.9 6) Water is delivered through a cast iron pipe from point A to point B. Point A is located at an elevation of 250 m and is at a pressure of 200 kPa. Point B is located at an elevation of 100 m. Find the minimum diameter of pipe required to deliver water through the pipe at 0.5 cubic meters per second, maintaining a pressure at point B of at least 150 kPa. The pipe length is 500 m. 7) Water flows through a concrete pipe 3 ft in diameter between reservoir A and reservoir B. The surface of reservoir A is at 800 ft while the surface of reservoir B is at 300 ft elevation. The length of the pipe is 1000 ft. Calculate: a. the head loss through the pipe b. the flow rate in the pipe 8) A 5" diameter pipe, 80 ft long, with a half open gate valve, connects two reservoirs with an elevation difference of 30 ft. The pipe is made of commercial steel. To maintain the flow rate of at least 500 L/min, what is the maximum number of flanged 180 degree return bends that could be included in the system?
