Thanks for your help anyway - you seem like a genuinely good man. I have to admit though, cannot get my head round it - I understand that we should look things up in books but I must have looked in about 20 now with nothing. My lecturers have been no help - I guess the hunt continues.
Good...
Can I apologise - I was unaware of the policy. I am really sorry - I have asked my lecturers and they have been no help. I didnt mean this to be like this. I am genuinely sorry, please forgive me - I just dont want to get in trouble
Would it help if I attach pictures of the lab script and the graphs that I got? We make a lot of assumption as this is only my first year lab report so. Nonetheless, appreciate your help. I thought it was choked flow also.
Doing an experiment. Plotting mass flow rate against pressure. Is linear for supersonic speeds but curved for subsonic speeds and dont understand why there is a change?
Any ideas?
