1. ### Feasibility Study

@CWatters I'm just trying to find the style that people have proposed this type of tender in, but I cannot find anything online (apart from 1 which is quite bad) in regards to bids to this type of tender. All I can find is the invitations to tender. Do you know if there are registries online...
2. ### Feasibility Study

Dear all, I have been searching for quite a while in regards to this topic but cannot find an answer that suits my question, which is: How would someone go about creating a tender bid for a feasibility study? How can you determine the cost of a feasibility study without actually doing the...
3. ### Buoyancy of Oil in Water

Awesome, thank you for your help! One last thing, if I were to take my balloon 1000m under water, would there be a difference in the forces? or would they act the same. As I know that as you go deeper there is a pressure differential as Simon stated, would this apply more force onto the balloon?
4. ### Buoyancy of Oil in Water

That makes sense, to reiterate: Fbuoyancy > Fballoon-weight -> Balloon will rise to surface Fbuoyancy < Fballoon-weight -> Balloon will fall to bottom. In the case of 1 m3 of oil in water, as you stated Fbuoyancy = 9.8*1000kg = 9800 N & Fballoon-weight = 9.8*850kg = 8330 N. Therefore...
5. ### Buoyancy of Oil in Water

Thank you Simon & leright. I was thinking along the same lines in terms of the density difference between the water and the oil would contribute to the buoyancy force of the balloon. See the form of Archimedes' Principle I have observed only allows you to account for one fluid density, and...
6. ### Buoyancy of Oil in Water

I have a hypothetical scenario I'd like to try understand, and I cannot find anything of the sort online nor in the forums. If I have a balloon of 1 m3 filled with oil, of a density of 850 kg/m3. Now I place this balloon in a body of water and tether it to a fixed point, how can I find the...
7. ### Water Pressure Calculation (Limited Information)

The piping in which I'd be using ideally will be clear vinyl tubing, which I'd assume has a much lower surface roughness than something like iron tubing which may have a rougher surface due to machining processes. But I will take into account what you have stated in the future, thank you mate...
8. ### Water Pressure Calculation (Limited Information)

Is it possible to find the pressure of water that leaves a pipe of certain area/diameter given only the flow rate of the water itself? OR the requires piping diameter/area given the pressure that I desire. I'm trying to design a system that requires relatively high pressure (for spraying)...
9. ### Tower out of paper that would support a textbook

For further information on this, OP, research properties of plane areas and radius of gyration specifically.
10. ### Tower out of paper that would support a textbook

If I were to attempt this project I would investigate and most likely construct vertical cylindrical pillars of paper (most likely multilayered, glue sheets to each other) to support the textbook. Edit: make these hollow.
11. ### Nuclear Engineering in Australia?

Nuclear Engineering in Australia?? Hi, im currently in my last year of highschool and i'm doing all the subject that will allow me enterance into universities in my state to study engineering. I'm from western australia. Does anyone know any information on what engineering course leads into...
