Ok, thank you :)

Thanks you very much for the assistance :) - - - Updated - - - I`m sorry, I didn`t realize that this was a judgement forum? I`m after returning to education after 8 years as a construction worker and am now currently studying to be a mechanical engineer on night courses. My ability in fluid...

So would I be using Force = mass x velocity Therefore F down = F up Therefore mv = mv ?? I have no model for air resistance.

Hi All, I am struggling with the question (attached) and was hoping to get some guidance and explanation on how to solve it. I`m thinking that it is force down is equal to force up? But I could be wrong. Any help greatly appreciated. Regards, James

Hi All, Cannot seem to figure out the question below. I`ve attached an image of the question. I basically need to find the mass of the weight W. The hinged gate will open when the water height is 12ft. The gate is a 5ft wide L shaped gate, hinged at point A. I`ve gone down the line of CW =...

Hi All, Could anyone advise on how to answer below question (attached). I am struggling big time on this. Thanks in advance.

Thank you very much for the reply. It is a level 7 degree (an ordinary bachelors engineering degree), so we have not just yet touched on integration, but I am sure this will come. How I did it was for the average pressure I got Pavg = density x gravity x (height/2) I then got the force by F =...

HI All, I have been out of education a long time and am now back at college. One of my modules is Fluid Dynamics and I am beginning to struggle with the basics and could really use your help. I have attached a snip from one of the example questions below given to me by my lecturer. For part...
