I've made an account just to tell you that it is UMS and not Ucas points lol.
Anyway thank you for the averages. I personally think that the A* would be around 55 for Unit 5A and 57 for Unit 4.
Oh yeah Silly me, I do know that so haven't got a clue why I put ucas.... Think it's been because I've been looking through my 'ucas' folder this morning lol!
Yes, I think B-C should be included. Basically, you had to calculate the area of the loop. Well, because I missed 5 mark question out, I have no idea what the boundaries will be. Lol... Hope it will be lower than last year, coz I need an A*......

Right good...did you? I did the area under not just the loop...said net, so did the whole thing lol... Yeah me too...where for for you? Imperial for me...

I do applied and heres some of the maths answers i got god knows if they are right, anyone get similar??
3671 revolutions 5.52x10^-3 1.43x10^-3 430 75 for graph area 15750 0.63 or 63% for efficiency 7.62x10^7
Same bar the P-V graph which I got wrong I believe, then ovbiously power after that...got the same efficiency for last q but diff number after? Can't remember what it was...

Not saying I'm right but.... B-C was horizontal I think. So constant pressure. So no compression so no work done ON the fluid. That was my reasoning. Hey ho.

I thought cos work=p*change in volume, so included it...but yeah, hey ho

Sweet at least that is a majority though Last questions i just rearranged efficiency =input/output cause it gave you output and efficiency =0.63 don't know if its right though??

Yeah exactly...I got a number with a slightly smaller power of 10 I think...same method I think tho...not too sure tbh
