1. Use the continuity equation and bernoulli equation to calculate the flow speed and the pressure in the construction in the pipe as well as the speed and pressure in the wide section of pipe.

2. Calculate percent difference value for your calculated values and the measured values.

Answer 1

Left sids readings U= 6.3 m/s Area of left side=AI A, = TX (1:25) pressure = 102.842 kPa = 4.gom2 4. こ 1.2265 m2 Right a side readings P2 = 133.315 kPa Area of side right= IT x 4.25 ER 0.4 mis = 14.179 m2 © Density of liquid und used = 1500 kg/m3 As we know AN = Ak Vz- 1.2265 X 6.3 AVI A2 - 14.179 =0.54 mis Calculated value Expt value "= 0.4m/s teoror: 10.54-oogl 1.4 LX0 = 25% 0:54 il) Bernoulli theorem at instant height, kike is horizontally Pi + ť8 vp = h + Ź 9 v² PE Pi + 2 Pv2 - 192² = 10 x 102.842 + 4x 150046.3 - 0.4)
