    Predicting Heat Transfer from a Pipe: Using Fourier's Heat Conduction Equation

    This is a great contribution Mapes. Thank you. So the desity and specific heat capacity are for water. These values are temperature dependent, although as long as the water doesn't lose too much temperature along the pipe these values can be looked up on a table. Are the density and...

    Predicting Heat Transfer from a Pipe: Using Fourier's Heat Conduction Equation

    Good suggestion re: PDE Mapes. I've turned Fourier's heat law into a first order differential equation: \frac{dT(x)}{dx} = \frac{k(T_i - T(x))}{404301.5752 \cdot r_i \cdot ln(\frac{r_o}{r_i}) \cdot v_w } If we re-arrange things so that it is in the form a dT(x)/dx + b T(x) + c = 0 I...

    Predicting Heat Transfer from a Pipe: Using Fourier's Heat Conduction Equation

    Your point is well received Mapes. I made an error above: 251,327 cu.ft of water is 15,689,592 lbs This makes a BIG difference, since the temperature gain would be 0.15C. It also means that decreasing the flow rate by ten fold, results in 1.54C change, which makes more sense. There is...

    Predicting Heat Transfer from a Pipe: Using Fourier's Heat Conduction Equation

    Here's what I did and someone can tell me what is wrong with it. 1. Calculate Q using Fourier's Heat conduction equation (see my post above). That give me the heat transfer along the length of the pipe in unit BTU/hr. 2. Get degrees celsius heat units per hour (C HU/hr) by dividing BTU/hr...

    Predicting Heat Transfer from a Pipe: Using Fourier's Heat Conduction Equation

    I am trying to predict the temperature of water coming out of a pipe. I know the temperature of the water going into the pipe. I know the material and characterisitics of the pipe. I know the ambient air temperature. I have explored Fourier's Heat Conduction \mbox {\Huge Q= $\frac {2...
