Flow rate of water = = = 8.824x10-5 m3/sSample Calculation (cross section A):Bernoulli equation:ViB = ViB = ViB = 0.243 m/s

Continuity equation:Ai = Ai = Ai = 5.31 x 10-4 m2Vic = Vic = Vic = 0.1662 m/s Therefore, the difference is = ViB - Vic = 0.243 m/s - 0.1662 m/s = 0.077 m/s Experiment 2(flow rate: medium)Volume (L)3
