    Calculating Temp Difference in a hot water tank

    Thank you for your reply. I really don't know very much but imagine that if you circulate hot water through a coil at the bottom of a tank that heat will be passed to the surrounding water and will rise to the top. Only when the system has reached a steady state will both temperatures be the...

    Calculating Temp Difference in a hot water tank

    I have a central heating system which passes hot water in through a copper coil pipe to heat water in a sealed tank. The warm water rises naturally with no mechanical agigitation. My question is if the coil is at the bottom of the tank what is the approx difference between the temp at the bottom...

    Can You Solve n to the Power of n = 240?

    Thank you for your interest. In the problem n is an unknown number. So it is a number raised to its own power. It must be less than 4 as 4 to power 4 = 256. If we don't know the number we can't know the log. Greetings Alan

    Calculating Temp Difference in a hot water tank

    I want to calculate the difference in temp between the bottom & top of a hot water tank, Presumably the height of the tank, the diameter, the actual temp and time would be the variables. I will assume no heat loss. The heat input would be at the base of the tank.
