Questions on Fluid System
Question
Given the following fluid system, where both the top and bottom tanks are open to the atmosphere and there are two piping paths from the top to the bottom tank path A and path B, that join at point C prior to discharge into the bottom tank at point D.
· Known quantities: all pipe segments have the same diameter, "D" and the same roughness factor, “f”
· Assume incompressible, isothermal flow of a Newtonian fluid.
· Both elbows have the identical friction loss coefficients, Kel
· The discharge nozzle at point D has a friction loss coefficient of Kdn
· Other dimensions are shown on the diagram.
a. Assume that the valve on line B is closed. Develop an equation for the velocity exiting the pipe, point D, in terms of known quantities (indicated on the figure or in the assumptions, listed above).
b. Assume that the valves on both lines A and B are fully open and that the friction loss coefficient of the tee at point C is zero. Is the pressure drop through line A (from the tank to point C) greater than, equal to, or less than the pressure drop through line B (from the tank to, point C). Explain the reasoning you use in. choosing your answer.
c. Assume that the bottom tank is totally enclosed and that the pressure inside the tank is maintained at pressure P1 Assume that the valve on line A is closed. Develop an equation for the velocity exiting the pipe D, into the tank at point D in terms of known quantities.
Summary
The question belongs to Mechanical Engineering and it is about fluid systems. Two tanks in a fluid system are filled with fluid. Various questions about this fluid system have been answered in the solution with detailed calculation.

WHAT OUR STUDENTS SAY
The topic I had selected for my dissertation required to include a report on the local markets of New South Wales. It was difficult getting help online as the data available are mostly generic and difficult to understand cohesively. Moreover, the majority of the online dissertation writing services online are located abroad somewhere in USA or UK. I was happy to see that HwA has dissertation writing helpers from not only Australia, but New South Wales itself and they cater specifically to students like us, who are from or studying in Australia.

I needed urgent help with my Labor Economics Assignment essay. The other online help service that I was using had produced an extremely unsatisfactory essay and I was in desperate need to make it right. I did not even have more than a day to fix it. But when I approached HwA they were up for the challenge and boy did they deliver! I passed in my assignment and even managed to be in the top ten of the class.

I desperately needed help to understand the topics under public works engineering and did not know where to turn to. Thankfully one of my friends suggested taking the online civil engineering tutoring sessions with HwA. The online tutors not only helped me understand the concepts but also provided reference material and notes to write the assignment essays.

The accounting assignment due for my term end evaluation had to include data and examples from Wellington businesses. So when I mentioned this special requirement of mine to the customer care executives at TheReliableTutor they immediately paired me with an accounting assignment expert who is from Wellington and has himself studied from the Victoria University of Wellington. Needless to say I topped the class and the professor was very impressed by the quality of the assignment.

I was marveled to find out that HwA offers such specific subject related nursing assignment solution. I always aimed to be a oncology nurse as the subject itself triggered my sense and passion for caring patients in need and when I saw the experts here in HwA dealing with the subject, I felt more inspired. I regularly took help and even now during my DNP I take constant help from the oncology nursing experts.

hi can anyone help or guide me to my assignments. thanks
This solution is perfect ...thanks
Hello Allison,I love the 2nd image that you did! I also, had never heard of SumoPaint, is something that I will have to exolpre a bit! I understand completely the 52 (or so) youtube videos that you probably watched. Sometimes they have what you want, sometimes they don't! However, it is always satisfying when you are able to produce something that you have taught yourself. Great job!Debra 0 likes
