I does ask for the velocities I forgot to post that part thanks a lot!

That's interesting and It makes sense. It could well be that the flow rate has once again been mixed up with velocity of flow. Ill check with my tutor.

Help with flow rates... part 2 Homework Statement A convergent divergent nozzle has an initial diameter of 1m this then reduces in size to 0.5 and finally expands to 2m the initial flow rate 22 m^3/s and the relative density of the fluid is 0.45 Homework Equations The...

That makes sense. I used the wrong method there. Thanks for your help in solving this anyhow. I have anther question that ill post up that I think I may have messed up on we shall see.

Just a bump, If someone can clarify the reason whyI have two answers for the velocity of flow 8.1499 and 62.5? And which method of getting there is correct! Im nearly there!

Ah yes let me correct that 0.866x8.1499x1.227=8.65 Kg/s The 62.5 I used first by mistake, i know it sounds silly but what is that? I worked it out above, I referred to some previous notes I had. it was from an example wit a tube that had multiple diameters and we had to work out the...

Now onto part B. This should be simple. I think I'm ok with mass flow rates... Famous last words! So to get the mass flow rate I take the relative density given as 0.866 and multiply it by the velocity I worked out. Presumably at the midpoint. And then multiply it by the surface area...

Ok That make sense. I think I'll stick with numerical values for now. It might be longer but my head may explode If I do anything else!

Thanks for clarifying that. If I had the right information to start I night not be struggling as much! So instead of flow rate, it's velocity of flow. In this case. Thanks! Could you just explain this par not quite sure what's going on! Thanks a lot

Ok so considering the fact that the flow rate is 10m/s through the 0.5m diameter. I would work out the surface area of the 0.5 diameter ∏X0.5^2/4= 0.1963m^2 And then divide the surface area of the midpoint. 1.227m^2 into the surface area of the 0.5 diameter 0.1963m^2...

I think you are correct there. Am I right in saying it would be flowing at 10m/s through the 0.5m diameter. If that's correct there is no labeled diagram but that's what we'll assume.

In my notes. I have flow rate written in m/s this is how we have been taught not m^3/s. The question A conical nozzle expands from 0.5m to 2m in a distance of 6m, the flow rate is 10m/s A) calculate the flow rate at the midpoint along the nozzle B) if the fluid has a relative...

1. The problem statement, all variables and given/known A conical Nozzle has a diameter on one end of 0.5m and 2m on the other. The nozzle is 6m long. The flow rate is 10 m/s. or 10m^3/s We are assuming that the liquid is in compressible. 1. Calculate the flow rate at midpoint...
