A window with a height of 1.2 m and a width of 2 m, consists of 2 pieces of glass with a thickness of 3 mm with a conductivity value of 0.78 W/m.°C. The two glasses are separated by air with a conductivity value of 0.026 W/m.°C of 12 mm thick. The window is used to separate a room from its surroundings. If the room temperature is kept constant at 24 °C and the ambient temperature is -5 °C. Convection coefficient on the inside and outside of the window respectively is h1 = 10 W/m?.degrees celsius and h2 = 25 W/m?.degrees celsius. Ignore the radiant heat transfer. Determine the transfer rate heat that passes through the window.

QUESTION 2 Figure 2 shows an ima ge of a house located near to a lake, further away from a windmill. Passive cooling also known as one of renewable resources. House Lake Wind mill #196347897 { Image courtesy : https://adobe.ly/3130M17) Explain in brief the difference between passive cooling and active cooling in the context of renewable energy. Include list of reference in your submission (Wikipedia are not accepted). а. b. Based on Figure 2, show how it is possible to implement passive cooling for the house. In your answer, justify for every decision taken such as: i. Location of input source ii. Location of out put source ii. Method to improve the air flow
A child opens the door of the freezer that is turned off, to observe its operation. If the ambient temperature is 30°, what will be the behavior of the internal temperature of the freezer when it is opened and why? a. does not change, since there is no material between the environment and the interior of the freezer for heat exchange b. is increasing, because the convection between the environment and the air inside the refrigerator does not transfer heat from the outside to the center c. does not change, since there is no contact between the surface of the meat and the external environment d. increases, because sunlight falls on the meat, increasing the energy. Then, when turning on the freezer again, it is observed that the back of the freezer gradually warms up, and remains warm during the operation of the machine. The amount of thermal energy emitted by the freezer must be: a. equal to 0; the heating is due to a problem with the freezer b. Less than the energy drawn from inside the…
