Entropy

In physics, entropy means the amount of disorder or the degree of randomness associated with a thermodynamic system. The system is not self-organized when the entropy of the system is high. For instance, when a system is at an elevated temperature, its molecules are in random motion, vibrating and colliding with each other. During this scenario, the probability of finding a molecule at a particular place twice, is low. Under this circumstance, the system can be said to be in a high entropy.

Question

Please I want to get the solution in 40 minutes. I have a test

Example 5 Consider a 0.8-m-high and 1.5-m-wide double-pane window consisting of two
4-mm-thick layers of glass (k = 0.78 W/m . °C) separated by a 10-mm-wide
stagnant air space (k = 0.026 W/m °C). Determine the steady rate of heat
transfer through this double-pane window and the temperature of its inner sur-
face for a day during which the room is maintained at 20°C while the tempera-
ture of the outdoors is -10°C. Take the convection heat transfer coefficients on
the inner and outer surfaces of the window to be h = 10 W/m2 . °C and hz =
40 W/m2. °C, which includes the effects of radiation.

It's saying this is not correct. Thank you for your help.
Thank you for your great effort but please i need solution by hand written and number of table at step by step thank you
could you plz take a photo of the solution, the solution above isn't clear, the words are all put together so i can't quite get it.
Paula has worked for Brindle Corporation for 3 years. During this time, she has worked as a machine operator/cell leader in various work cells. Recently, the plant went to mandatory 12-hour shifts and plans to remain on this schedule for several months. Paula’s present work cell is manufacturing 3-inch diameter exhaust tubes that are made from stainless steel. These tubes get a hole punched in them, a flange welded on, and burrs ground off. The pipe then gets placed into a gage to check that it was made correctly. (The tubes weigh about six pounds.) Paula has been performing the welding operation. She leans into the machine and loads the part into a fixture then positions the flange. Both pieces are clamped (using hand clamps) into position and the machine is cycled by depressing two palm buttons. The gaging operation requires placing the finished part into the gage and clamping it (using hand clamps) into place. A pin is depressed to verify the position of the hole and a…
