So, I've obtained a graph of lab data an it's a plot of thermal resistance versus pressure. Pressure on the x and thermal resistance on the y. If I plot all the points, there doesn't seem to be any trend. The y values are just as likely to decrease as they are to increase with increasing x...
Well, we did take measurements of Q throughout the experiment but that was about it. The first question, verifying the conservation of momentum just seemed to be calculating the Force on the plate via the moment balance and then seeing if this matched $$F = \rho Q (V_1 - V_2cos\theta)$$
Where...
Thanks for that. I actually found something in my notes stating that the value of ##C_C## for a nozzle is approximately 1. Is this correct? If so, how would I go about calculating ##C_V##?
That isn't the first page of the handout which we were given. I only posted that to show the equipment set up. I'll post all the pages of our actual handout (there's no reference to ##C_V## or ##C_C## anywhere). No, we've never come across these coefficients in class. I looked up ##C_V## and...
1. Homework Statement
We recently did an experiment involving the impact of fluid jet on both plane and cupped surfaces. See the diagram attached for the experimental set up. We were asked to 1) verify the conservation of momentum and 2) calculate the discharge coefficient of the nozzle from...
I have absolutely do idea how I'd even begin to go about doing that. I've just begun 2nd year Process Eng. so my knowledge of that sort of stuff would be limited. Like I said, it's only to be a very short project. We have 1-2 weeks to do it. Thanks for the input though. Any simpler, less...
1. Homework Statement
So, as part of a numerical methods module that I'm taking I have to write a report and MATLAB program which deals with some sort of engineering/physics based problem. The report essentially just outlines and discusses the problem. It's the initial idea which I'm looking...
Thanks for the reply. RH is the defined as the ratio of partial pressure to saturation partial pressure at a given temperature (multiplied by 100 for a percentage). I could always just use this, knowing the saturation pressure of water at the given temps, to find my final value of RH. I was...
1. Homework Statement
The air emerging from a hot aqueous process at a temperature of 45°C, passes over a surface which is gradually cooled. It is found that the first traces of moisture appear on this surface when it is at 40°C. Estimate the relative humidity of the air leaving the dryer...
So, is your first part for the max experimental stress? Like, I find the max stressed area and then divide the maximum load by this? I'm not sure if I follow.
Well, the loads act at along the beams length, 350 mm from the ends. So, the bending moment will be -W/2 x 0.35? I've already calculated...
1. Homework Statement
1. Take dimensions of the beam (B, D, web and flange thickness, L) – T- cross section
2. Take the beam span geometry and material properties from the instrument
3. Ensure the beam and load cell are properly aligned and apply a positive (downward) preload to the beam of...
