I need help with this Fourniers Law problem. Thank YOU (a) Let's say that it is chilly T, outside, and a much warmer T; inside. If we were to have a single-pane window(which is made of a single piece of glass) with a thickness w and an area A, write an equation for (i) the fluxof heat Fh across the window; and (ii) the flow of heat Qn across the window. What are the units of Fh andQn?(b) Determine values for F, and Qh assuming that T.-15°C, T; = +20°C, w == 7 mm, and A = 0.8 m².(c) If there are about nw(kWh), estimate the heating bill per month (in US dollars) just to offset losses through the windows? [Andnow you can see why double-paned windows, which are much more insulating, are normal in cold climates!]20 such windows in the house, and energy costs 10 cents (US) per kilowatt-hour

Solution: a). (i). According to Fourier law, the flux of heat through the window is directly…

a) Let's say that it is chilly To outside, and a much warmer T; inside. If we were to have a single-pane window which is made of a single piece of glass) with a thickness w and an area A, write an equation for (i) the flux f heat F across the window; and (ii) the flow of heat Qh across the window. What are the units of F, and b) Determine values for Fh and Qh assuming that To = -15°C, T; = +20°C, w = 7 mm, and A = 0.8 m2. c) If there are about nw = 20 such windows in the house, and energy costs 10 cents (US) per kilowatt-hour kWh), estimate the heating bill per month (in US dollars) just to offset losses through the windows? [And ow you can see why double-paned windows, which are much more insulating, are normal in cold climates!]
