Question

13. 3.6×10-3 m3 of water flows out every second from the orifice with a diameter of d=50 mm installed on the side of the tank in Figure 5.34. The minimum cross-sectional area of ​​the jet was d=40 mm. Find the contraction coefficient ??, velocity coefficient ??, and flow coefficient ? of this orifice.

with explaination please

46cm zot dt

Answer 1

given, Q = 316x16?m/s flow Rate h-46cm = - 0.46 m d- 50 mm d'=0,040 m. d =0.0som Contraction coefficient ca d'= 40 mm Area of Jet at vena contra Area of orifice 7 67² (d, ² d² 2 = (40² - G=0.64 2 Anower Velocity coefficient card ca Actual velocity v Theoretical velocity Nigh 42 here, Actual velocity A .
