Question

1. Note that we assumed that the speed of the water at Point 1 was zero. In reality it is a small positive number that decreases as the water drains. Qualitatively, how would the slope of your graph change if you had kept this term? Would the slope increase? Decrease? Stay the same? Support your answer using Bernoulli’s equation.

2.The continuity equation is a statement of mass conservation that the volume flow rate Q must be constant, so we can write Q=A1v1=A2v2 where A is the flow cross-section area and v is the fluid speed. According to the continuity equation, how should the speed of the flow at the hole in the cup compare to the speed of flow at the top of the cup? Note that the area of the hole and the circular area of the cup are the appropriate cross-sections to use.

Answer 1

I hope this will be helpful. I'm sorry I can't understand question no. 1and I think there are some missing information. So provide it I will provide you with the solution for question no. 1 too. Thank you
