Dear members,
I have been asked about a hypothetical question as per following but I can't find any logical answer:
Question #
There is a vertical pipe with 1,000 m length and 12 inch dia. The pipe is full of water, two valves have been installed in elevations of 1 m and 1,000 m. When the top valve is in the closed condition, if the bottom valve has been opened, answer the following questions:,
1-How much water will drain from the pipe?
2- Will all of the water drain from the pipe?
3- What is pressure in elevation of 1,000 m just after opening of valve?
4- What is the water velocity during draining?
Appreciated if you could share your knowledge and experience about above question.
