# Can someone re-arrange this for me please watch

1. Can someone please re-arrange this formula for me and put Ts as the subject please?

V =(Q/(Ts-Tr)) * ((273+Ts)/358)

Sorry to ask here but I know you guys love this.

Many thanks in advance and plus rep and stuff
2. The idea is that people point you in the right direction with the question and give hints, not that they just do it for you. :P
3. Ok, heres what I got.. Ts = (273 + (358V/Q)*Tr) / ((358V/Q)-1)

Is it right?
4. Whats the matter guys? too tough?

I didn't get that answer when I tried.

Original equation:

Start by multiplying the fractions together then get all the expressions with Ts in over to one side.

EDIT: realised I wrote x instead of V in equation
6. Ts = (273Q + Tr) / (358V - Q)
Ts = (273Q + Tr) / (358V - Q)
I'm not sure if that's right either mate.
Any more suggestions, seems alot of us are stumped.
8. starofale what did you get?
9. I apologise I did make a mistake lol. Here is correct answer with method:

V = Q/(Ts-Tr) * (273+Ts)/358

Multiply by 358 and divide by Q to get

358V/Q = (273+Ts)/(Ts-Tr)

Multiply by (Ts-Tr)

358V(Ts-Tr)/Q = 273 + Ts

Now bring all onto one side

358V(Ts-Tr)/Q - 273 -Ts = 0

Multilpy by Q

358V(Ts-Tr) - 273Q -TsQ = 0

Add 273Q to other side and factorise out Ts

Ts(358V - Q) -358Tr = 273Q

Add Tr to other side and divide by 358V - Q for answer

Ts = (273Q+358Tr)/(358V - Q)

Hope this is right this time!
10. OP you do realise you can just substitute arbitary numbers into the question and your solution to check it..
11. looks good spread the logic!!! Well done indeed.
12. I realised its the same answer you have now, so we gotta be right, right?!
13. hang on there....

Tr = 20
Q = 70
V = 32000/3600
Ts = 25.69

So everyone so far is wrong :P
14. Noo, can't be! confused over here, I think you are definitely right logic
15. What is Ts, physically? Is it freezing point in kelvin of something?
Ts = (273Q+358Tr)/(358V - Q)

Hope this is right this time!
Yes this is what I got.
17. and it does work if you sub. in some numbers
