Q1. Find the heat flow rate through the composite wall as shown in Fig. bele Assume one dimensional flow & the area is variable for each layer. Where: 60°C kA = 152 W/m°C, kB = 31 W/m°C, %3D 3 cm kC = 68 W/m°C and 7 cm %3D kD = 53 W/m °C. 400°C A 10 cm 5 cm 8 cm 3 cm D. BC
It is required to air condition a factory building (27m x 18m x 4m). The 27m wall is type B and facessouth. The following date is available: Two glass windows in south wall 3m x 1.5m each with internalshade, Lighting load is 20 Watt fluorescent per m2 floor area ; The inside air conditions are, DBT=24 oCand RH=50%. The outside air conditions are, DBT= 40 oC, WBT=30 oC. Other related data are: dailyRange (DR)=18.0 oC, Uwall =1.4 W/m2 k, Uglass=3.5 W/m2 k, Scglass =0.7, occupancy = 8 persons doing lightbench work and, CLFoccupancy= 0.75. The building is of heavy construction with light color located at 32 N.Calculate the building cooling load from the south wall, windows, lighting and occupancy on August at4.0 p.m.

With the calculated U value for the windows find out how much power needed to maintain 20°C in a home with outside of 0°C based on the following: the house having a square footprint 17 m by 17 m, walls 2.5 m high (Uwalls = 0.152 each of the four walls hosting two windows, and each window having an area of 2 m². The entry door area is 2.5 m² (Udoor = 0.65- ). What are the heat loss rates for the installed windows, the door, the walls, the ceiling, and the floor? What is the overall heat loss rate of the home? m². C 1. What do these calculated heat loss rate values mean? 2. What is the definition of the passive house? 3. What does the U-value represent?

Sipho’s mother is making a fire in the stove inside a shack using coal. A fan is used to extract the flue gasfrom the fire via a chimney made of zinc material. The wall thickness of Chimney is L=4mm and the walltemperature of the chimney on the flue gas side is T_si=60˚C. Sipho, playing outside next to the chimneyexperiences an ambient temperature of 20˚C. The surrounding temperature is T_sur=35˚C and the emissivityis ε=0.95. Assume the convection coefficient is 20W/m2K and the chimney is grey material.Under these conditions determine the outer surface (air side) temperature T_so=? of the chimney.
