4. A pressure gauge attached to a 150mm diameter pipe at a valve box assembly registered a pressure differential of 31.2 kPa on the gage. What is the flow? 5. Water is siphoned from a tank at the rate of 0.71 m3/sec. The flowing end of the siphon is 5.6 meters below the water surface. There is a 0.25m friction head loss from the tank to the summit of the siphon, and an equivalent of 1 Velocity Head is lost in friction from the summit of the siphon in the tank to the end of the siphon. The summit is 1.25m above the water surface. Find the pipe diameter. What is the pressure at the summit? (please give all formulas you are using and calculation step by step.)
