that was very helpful thank you all. Its also helpful to see the analogous method in circuits, but i do not really know how to create equations with what you have shown in the diagram.

not exactly... dQ = increment of heat = mcdT? i thought it was Q = mcdT how does the dT change in this situation?? where is k(T-Ta) come from exactly?

I see. would it be wrong to try to find an average heat loss rate using the current information? can you help me set up for the process down to the 32F point?

so... no actual answers to any of my direct questions...? thats gg thanks anyway everyone.

well i didnt know if it mattered or not but I think ambient air is 20 deg F. in that question. can somebody clarify Q in Q=mCdT for me please? Is it thermal energy in BTU or is it a rate? (btu/hr)

I believe i may need to show work on how i got that number? Looks like that's volumetric specific heat? where is the time portion?

Hi all, i have a problem here I need to solve asap. Homework Statement I need to find out the Time it takes for 6900 gallons of WATER to go from: 55 deg F. to 32 deg F. 55 deg F. to 20 deg F. ambient air set at 20 deg F. if needed The heat loss rate is 750 Btu/Hr/degF. Homework Equations...
