Inside a wall measuring 35m, There are 2 (glass thickness 1 cm) 4.5 m single glazed windows with a heat transfer coefficient of K.
Ambient temperature on the inside of the wall is 11 C, outdoor temperature - 811 C, the external and internal convection coefficients are αoutdoor= 29 W/m2 C, αinside = 9.6 W/m2 C. Wall from outside to inside, 2.9 cm thick exterior plaster with k = 8.7 W/moC, 14.5 cm thick reinforced concrete with k = 0.8 W/m C, It consists of 1 cm thick k = 0.6 W/m C gypsum honey and internal plaster.
A-) Find the total heat loss.
B-) How many cm of insulator (styrofoam) material with k = 0.04W/m C should be used to reduce heat loss by 80%?
C-) Calculations will be made for single and double glazing?
D-) Calculate the required amount of fuel before and after the insulation?

Give the missing values in the question. no problem C = ( DEGREE, C° )
