Figure 16-29 shows liquid discharging from an orifice in a large tank at a distance h below the liquid surface. The tank is open at the top. (a) Apply Bernoulli's equation to a streamline connecting points 1, 2, and 3, and show that the speed of efflux is This is known as Torricelli's law. (b) If the orifice were curved directly upward, how high would the liquid stream rise? (c) How would viscosity or turbulence affect the analysis?

(c) The whole calculation is done keeping in view that the flow is streamline. When there is viscosity or turbulence there would be lost of energy. Thus, liquid stream would not rise to a height h.
