Law for tap water temperature Issues/simplifications: We never calculated / worried about the Reynolds number, so we don't know if we have laminar or turbulent flow, we assume that tank of water is insulated from the tube and the water inside always remains at the initial temperature, and that the outside of the tube is at constant temperature over its length. |

Law for tap water temperature Aye, and the math there is a bit more hairy. By the way, nice job with the use of MathJax - I think you're missing a grouping in the e^{-\alpha x} term, though (or I've missed a step in the integration, which is possible/likely). |

Law for tap water temperature Agree - this is the steady-state solution for classical heat exchanger problem. The original question implied that the temperature at the tap was changing over time, which it isn't. Or the question needs to be rephrased somewhat and both @Cedric and I are over-complicating the solution considerably. |

Law for tap water temperature Which water temperature? The tank, or the outlet water temperature? |
