To determine the flow through the siphon when h =4 ft and plot the HGL and EGL for the siphon conduit. Explanation Given: The height of siphon from the inlet ( h ) is 4 ft. The diameter of the siphon ( d ) is 8 in . . The temperature of the water is 80 ° F . Calculation: Consider the water is incompressible and inviscid and the steady flow state. The point A and B are open to atmosphere, the velocity at point A and B are zero. p A = p B = 0 Consider the capacity of water in the reservoir the velocity of the water at point A is negligible. V A ≃ 0 The datum passed through the Point B, z B = 0 The datum level at point A is, z A = 38 ft − 2 ft =36 ft Apply the Bernoulli's equation between the point A and B. p A γ w + V A 2 2 g + z A = p B γ w + V B 2 2 g + z B 0 + 0 + 36 ft = 0 + V B 2 2 ( 32.2 ft / s 2 ) + 0 V B = 48.15 ft/s The cross section of the point C and B are same. So the velocities at these points are also same. V C = V B = 48.15 ft/s Apply the Bernoulli's equation between the point A and C. p A γ w + V A 2 2 g + z A = p C γ w + V C 2 2 g + z C 0 + 0 + 36 ft = p c 62.4 lb/ft 3 + ( 48.15 ft/s ) 2 2 ( 32.2 ft / s 2 ) + 30 ft p C = ( − 1872 lb ft 2 ) ( 1 ft 12 in
