We know that Q (in Q=m Cp ∆T) is total heat delivered or removed to/from a system. Is there a mathematical convention for referring to the total amount of heat delivered in the course of a day? What notations would mathematically describe total thermal energy in a day?
I was thinking that ∆ in mathematics refers to change over a period of time. Would I then be correct to say [ ∆Q, subscript 'day'] to refer to all the thermal energy transferred in a day?
There is no such notation as per my knowledge - So I guess that you can go for ∆Q subscript 'day'
Thanks Hakeem,
I agree. I haven’t really found any convention. I think both ∆Q, subscript day (and also perhaps ∑Q, subscript day) would be mathematically correct. Thanks for your input.
I think you don't need a symbol or notation.you need a formula that links with time,I think you can use formula below for your purpose.
∆Q=(K*A*t*∆T)/L
Hi Antonios
Sorry I couldn’t reply earlier.
Yes you are absolutely right. The integral notation with respect to time is the best expression actually. I have just come back from meeting a professor who mentored me for my MEng and he is of the same thinking (although he says ∑q is just as good!).
Cheers.
