Calculating k Values for Pipe Insulation By Russell Peterson & Chris Mabey
Water Heater for the Developing World • Minimize heat loss in pipes outside of the fire
Problem • Find out if clothing would be a good insulator for pipes on the water heater. • Compare the k values for clothing to those of an emergency blanket and foam pipe insulation.
Problem Setup Plastic Bottle Twater Tsurroundings Insulation
Measured Temperatures and Transient Conduction Model to determine h
Measured Temperatures and Lumped Capacitance Model to determine h
Conclusion • Calculated k values • Pipe Insulation= 0.0212 • Shirt = 0.0015 • Emergency Blanket= 3.84 e -5 • Clothes have a good k value but they need to be thick to provide adequate insulation • Emergency blanket is an excellent insulator but would be difficult to obtain in developing countries.
