The water tank shown in Figure 1 below is being filled through section 1 at a velocity of 5 m/s. The discharge flow rate through section 3 is 0.012 m3 /s. Figure 1: Pipe Flow through water tank a) If the water level h is constant, determine the exit velocity v2 b) Give assumption to velocity at section 3 and determine the pipe diameter for section 3 (5 marks) (5 marks) c) If the water level varies (change), and velocity at section 2 is 8 m/s, determine the rate of level change, dh/dt . Assume d = 1.0 m. State whether the level is increasing or decreasing. (5 marks) d) Check whether the mass flow rate at constant level h is following the continuity equation concept if the water flows at constant temperature 25⁰C (5 marks)
