Hi all, i have a problem here I need to solve asap.
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.
Q=mCdT
Tf = 20 F
Ti = 55 F
m = 6900*8.35 (lbs)
c = 1? btu/lb/degF? (was a bit confused with this)
I have tried the formula many times but get the same answer... which I feel like is not very reasonable. Welcome any and all constructive help please =)
