Cheers for the feedback.
Yeh q-line.
So with the calculation of H and h.. with those equations you'd get what a function of x and y of the most volatile component to plot..
If you were to design a distil col and didn't know the feed conditions how would you go about starting. You know xd, xb, xf, R, Eq data.
Theres 5 potential q's.
Also how would u make enthpy diagram for PS.
Thanks.
Cheers. Ah yeh I know its easy enough to do by hand.. but yeh I'm looking for very accurate results. Thats the only reason I wanted to know if it could be done via a program.
Hey does anyone know what prgram you could use to draw a ponchon and mccabe diagram for mass transfer.
Particularly one that's downloadable :P.
Cheers.
what is your fluid?
How does it's density change with temperature?
what is your mass/volumetric flow rate?
Can you make any assumptions about either the inlet or outlet pressure?
How did you calculate your Re to determine turbulence without a velocity?
the fluid is an oil.
density is...
How do u calc pressure at each end of pipe if u know its turbulent and u don't know the length.
Just got viscosity, density, temp diff at one end, D.
Cheers.
Hey,
If you have 3 pipes of different diameter flowing into another.. what needs to be true for the head loss in the 3 pipes to all be equal?
ie Hf1 = Hf2 = Hf3
Cheers. :S
Been reading about aluminium alloys.
Could someone tell me why some alloys are heat treatable and others aren't. Or why certain alloys aren't heat teat treatable.
I'm assuming the non heat treatable alloy may become brittle? But yeh bit confused.
Thanks
Wow, this forum seems to be full of engineering brilliance :P.
Anyway can anyone help me with this.
The stages in sand casting to produce:
a) solid object that is thinner at the centre than at the ends
b) hollow object with two openings of diameters less than the component diameter...
In organic if you have more than one functional group.. how do you know which will react in preference?
In the attachment I've got an organic compound which has an ether and alcohol.
In terms of naming the alcohol gets preference.
It reacts with excess HI and the alcohol apparently...
Another question. If your given the quality coming out of the turbine.
Why do you use say H2 = Hl + xv(Hv - Hl) to determine a xv even though u hav one given?
Indicate briefly how the Margules' 3 suffix equations are derived for a binary solution.
ln gamma1 = [A12 + (B12 - A12)x1](x2)^2
ln gamma2 = [B12 + (A12 - B12)x2](x1)^2
Any idea how this would be shown.. :S
Basically what I'm trying to ask is if your just calculating P with the 3 equations and plotting against the the x1 and y1 in the given data table.
I've got a feeling you have to calculate new x1 and y1 values.. but for instance with the margules eq you can calculate a new y1 but u have to...
