If we have a tank of water and a hole or nozzle somewhere at a distance h1 from the top surface, the velocity of the water leaving the tank is v = √(2gh1). This is "Toricelli's Theorem"

Question: Ignoring friction losses, Let's say that the pipe runs out from this same distance but turns up and extends upward at a height h2. Now, what is the velocity discharging from the tank?

Would it still be v = √(2gh1) or would it now be v = √(2g(h1-h2))? In other words, how would we account for the pipe that extends upward a distance of h2? (remember--ignore friction losses in the pipe).

Remember how you defined h1? It's the distance from the top surface to the nozzle. When you go up h2, you've just reduced your original h1 by a distance h2. My take is that you now have a new, shorter, h1 and you use the same equation with this new h1. As you say, though, the new h1 equals the old h1 minus h2.
