    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

    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

    Ok, heres what I got.. Ts = (273 + (358V/Q)*Tr) / ((358V/Q)-1)

    Is it right?

    I didn't get that answer when I tried.

    Original equation:
    V=\frac{Q}{Ts-Tr}*\frac{273+Ts}{358}

    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

    I'm not sure if that's right either mate.
    Any more suggestions, seems alot of us are stumped.

    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!

    OP you do realise you can just substitute arbitary numbers into the question and your solution to check it..

    hang on there....

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

    So everyone so far is wrong :P
