Extracted text: 6- Discussion:- 1- Why is the value of the discharge factor (Cd)near of venture tube to one? or Q actual and Q thecoretical are close together. 2-Explain the relationship of the change in the volumetric flow of the fluid with the change in pressure drop(Ah), through the above tables at all speed of pump are the values as ascending or descending or otherwise? 3- What the relationship between (Q actual) at y- axis and(VAh at x- axis) discuss it? 4-Through the values ( Re, and Re, Number), explained the reason for the difference in values? 5-What is the benefit of using the Venturi device mode or what are its engineering applications? Notes:- Can be taken p= 999kg/m3 ,u=0.804x 10 kg/m. sec of water at 30°C.
