5 An irrigation siphon is a flexible tube of constant diameter D used to carry water from a supply ditch over a berm to a field to be irrigated,as shown in Figure P5.11.5. Neglecting all losses, calculate the ideal flowrate and velocity for D = 3 inches,drop = 10 inches, rise = 2 ft,T = 35 c Calculate the actual flowrate, assuming a discharge coefficient of0.56.
