Question

Question 3. Note that we assumed that the speed of the water at the top of the cup (Point 1) was zero. In reality it is a small positive number

that decreases as the water drains. Qualitatively, how is the slope of the graph of v2^2 vs. h affected by this? e.g. should the slope be steeper when h is large and flatter when h is small? Or vice versa?Or should the slope be unaffected? Support your answer using Bernoulli's equation.
