Heat Transfer Equation
Heat Transfer Equation
(OP)
I am looking to calculate the temperature of water inside a small pressure vessel. I have several thermocouples on the wall and have an average at different time increments. Purpose of this is so I can see how much heat the water absorbed. Thanks in advance.

RE: Heat Transfer Equation
If the outer wall temperature is constant then the vessel should be roughly in equilibrium with the surroundings.
The amount of heat absorbed or released by the internal fluid between steady condition 1 and steady condition 2 will be the change in temperature times mass times the heat capacity.

NO. If the system never equilibrates, then, by definition, the internal fluid temperature change MUST be lower than the external temperature change.
But how do you know that the fluid temperature never stabilizes? If you already know the fluid temperature, then what's the issue?

Shouldn't the internal fluid temperature be higher than that of the outer vessel surface?

Shouldn't you have told us that that the fluid was being heated internally or was hotter to start with?
