The room in the figure below has two sliding single glass 10mm aluminum window (U value = 6.7 W/m2.K). Each window is 0.8X1.3m with sill height 0.7m. The inside and outside design temperatures are 22C and 5C. Find: 1) Heat loss from the window (2 point) 2) Heat gain due to infiltration from the windows assuming $1= 0.9, S2= 0.7 infiltration coefficient K= 0.43 and air velocity = 6m/s. (2 point) 3) Assume the total heat loss of the room is 3000 w, find the number of cast iron radiator sections needed to heat this room and show its location on the drawing.
