Aroom contains four single-pane windows of size 5 ft by 2.5 ft. the thickness of the glass is 1/4 in. if the inside glass surface is at 60°f and the outside surface is at 30°f, estimate the heat loss through the windows 0ht

Explanation:

The given data is as follows.

           Area = = 12.5

             L = 0.25 in = 0.0208 ft     (as 1 inch = 0.0833 ft)

      ,        

               k (thermal conductivity) = 0.8

Formula to calculate the heat loss will be as follows.

               Q =

Putting the given values into the above formula as follows.

             Q =

                 =

                 = 14285.7 Btu/hr

So,

                  =

                  = 57142.8 Btu/hr

Thus, we can conclude that heat loss through the windows is 57142.8 Btu/hr.

adding or remove a gaseous reactant or product changes the concentrations. if the concentration of reactant or product is increased, the system will shift away from the side in which concentration was increased (i.e. if the concentration of reactants is increased, the system will shift toward the products. if more products are added, the system will shift to form more reactants). conversely, if the concentration of reactant or product is decreased, the system will shift toward the side in which concentration was decreased (i.e. if reactants are removed, the system will shift to form more reactants. if the concentration of products is decreased, the equilibrium will shift toward the products).
