2)The sound of a waterfall can add a sense of calm to a space. The owner of the pictured waterfall wantedto increase the sound effect by causing the water to develop turbulent flow 0.4 m from thetop.i)If the kinematic viscosity of the water in the garden at 20°C is 1.004 x 10-5 m²/s, whatflow rate would the owner need to use.Show your calculations.ii)What would happen to the point of turbulence in the winter when the temperature dops a few degrees,but flow rate is maintained at the summer value, explain your answer?

Ans 1. For turbulent flow Re≥5*105 Now, Then, required flow rate =12.55 Ac m3/s
