    Heat Transfer rate question

    It's been a while since I did heat transfer calculations and am posting hoping you guys can help me. I have a tank that contains 6 gallons of water at 85C. There's a cooling coil in the tank that has a surface area of about 90in^2. The OD of the tube is. 313in and a wall thickness of. 029in...

    Heat Transfer Equation

    I do not know the fluid temperature. I am measuring the outer wall of the vessel that the fluid is contained in. Shouldn't the internal fluid temperature be higher than that of the outer vessel surface?

    Heat Transfer Equation

    The temperature never reaches a constant. Is it a correct assumption to assume that the change in temperature on the surface of the vessel will be the same as the internal fluid? Just seems like the heat absorbed by the internal fluid will be lower than what it really is by this assumption.

    Heat Transfer Equation

    lol I apologize. What would be the best way to calculate the temperature of the water? I have the temperature of the outer surface of the vessel.

    Heat Transfer Equation

    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.

    Need Help with Plotting multiple lines

    I am plotting 6 curves on one plot. 5 of those will be using the left axis and the 1 using the right axis. Each line will have a different color. The code that I have is giving me colors that do not match up with the lines. M = csvread(filenameAndDir,1,0); t=M(:,1)/60; T=M(:,2); T1=M(:,3)...
