Of course, you can do all this graphically. Start with a source, say a candle, whose heat is fairly constant, and heat a piece of copper tubing with a known flow rate of water. Measure the water input temperature and measure the output temperature at various distances from the source after heating. You can plot the curve on graph paper and, using curve fitting, determine when the temperature falls by, say, 95%. All quite silly, really, tho. T
