Question
3.54 In the siphon of Fig. 3.60, h, = 1 m, h, = 3 m, D, 3 m, D, = 5 m, and the losses to section 2
are 2.6V /2g. with 10 percent of the losses occurring before section 1. Find the discharge and the
pressure at section 1.
3.55 Find the pressure at A of Prob. 3.54 if it is a stagnation point (velocity zero).
3.56 The siphon of Fig. 3.19 has a nozzle 150 mm long attached at section 3, reducing the diameter to
150 mm. For no losses, compute the discharge and the pressure at sections 2 and 3.
3.57 In Prob. 3.56 with losses from 1 to 2 of 1.7V/2g, from 2 to 3 of 0.9V3/2g, and through the
nozzle 0.06V?/2g, in which VE is the exit velocity, calculate the discharge and the pressure at
sections 2 and 3.
