Questions on Cube Filled with Fluid
Question
Given: A cube whose sides are length L. The cube is open at the top (exposed to an atmospheric pressure, PO), but all of the side and bottom faces are solid material. The cube is completely filled with a fluid. There is no motion in the cube.
A: Prove that the force exerted on any side face is greater if the cube is filled with water than if the cube is filled with air.
B: If L = 3 feet and the temperature of the fluid is 70°F, calculate the pressure at the bottom of the cube for each fluid, in atmospheres of pressure. The density of water is 62.4 lb/ft3. Gravity is 32.174 ft/S2. The Universal Gas constant is: R = 0.7302 (atm-ft3)/(lbmole-°R)
C: If the cube is located on the International Space Station and an external pressure, PO is applied to the open face of the cube (i.e. PO ≠ 0), prove whether the proof in Part A is still valid.
Summary
The question belongs to Mechanical Engineering and the question is about a cube filled with fluid at an atmospheric pressure PO. Questions such as, if the cube is filled with water what would be the force exerted. If the fluid is 70°F, the pressure exerted at the bottom of the cube and if the cube is located on International Space Station and an external pressure is applied, etc are answered in the solution in detailed calculations.

WHAT OUR STUDENTS SAY
Dimensions of fluids was a mind boggling concept for me and I really felt lost. Luckily, I came across HwA who not only helped me to go through the fluid mechanics assignments but importantly helped me understand the concepts of it which now coming to my use in my master degree as well.

I totally loved getting helped from a Melbourne based tutor via HwA as I believe someone from UK or the States could have understood the specifications required for my assignment. It is a marvellous website and I encourage all my fellow students from Melbourne to avail help from HwA as and when they need.
Amy Jones Student
Thank you so much guys…!!! The final product was very precise, thorough and was far beyond what I expected for. It’s simply awesome and best part is that I got top grades in the assignment. I am very grateful to TheReliableTutor.com.
Stuart Student
The management case study was based on a factory in Napier, which I am sure no US based or UK based assignment experts could have solved. I searched online for management assignment experts from New Zealand but was not being able to narrow down on one. Luckily, then I bumped into TheReliableTutor and found out that the management assignment experts are actually from New Zealand. The case study went well and so did the other management assignment solutions, for which I took help from them again.

The most fascinating thing about HwA is that they are very flexible in their approach. For instance when in order to incorporate my professor’s feedback I requested them to alter my existing assignment solution, they did it without hesitation and with no extra charge.

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
