Chiller Pipe Insulation CalculatorSystem InputsPipe Outside Diameter (ft): Outer diameter of the bare pipe. Pipe Length (ft): Length of pipe considered. Ambient Temperature (°F): Temperature of surrounding air. Bare Surface Temperature (°F): Temperature of pipe surface without insulation. Liquid Temperature (°F): Temperature of the fluid inside the pipe. Convection Coefficient h (Btu/hr-ft²-°F): Natural convection coefficient. Emissivity ε: Emissivity of the surface.
