PROBLEM 3.11 KNOWN: Composite wall of a house with prescribed convection processes at inner and outer surfaces. FIND: (a) Expression for thermal resistance of house wall, R tot; (b) Total heat loss, 9(W); (c) Effect on heat loss due to increase in outside heat transfer convection coefficient, ho; and (d) Controlling resistance for heat loss from house. SCHEMATIC: Plaster board, kp -Fiberglass blanket (28kg/m3), kb A=350 m2 -Plywood siding, ks h;= 30 W/m2.K T;=20°C 999 9 9 9 ho= 60W/m2.K, To= -15°C Lp=10mm*+=100mm* + Ls=20mm R 14 ASSUMPTIONS: (1) One-dimensional conduction, (2) Steady-state conditions, (3) Negligible contact resistance.
