Insulation density calculation
Nettetinsulation. Density may be increased to a point where the solids content of the insulation is such that the heat bridge of the solids overcomes the insulating effect … Nettetsize and insulation thickness based on ΔT. For example, for a 3" (76 mm) pipe with 2" (51 mm) insulation and ΔT = 60ºF (33.3ºC), the value for QP is 5.5 W/ft (10.8 W/m). THERMAL DESIGN- PIPES Step 3.Adjust for Insulation Table 1 (page 2) is based on ASTM C547 Fiberglas® insulation. QP, as found in the step above, must be adjusted
