You just graduate from college and find a job (yah! Congrats!). You buy a new house and would like to install solar panels for the house (thanks for going green!). The daily energy consumption of the house is 30 kWhr. The solar energy a standard solar panel can capture varies by location. In your area, the daily energy captured by a standard 250 W panel is 1.1 kWhr. How many Ds are the daily energy per panel and daily house energy use, respectively? How many panels do you need for your home (please round to an integer)?

Acommercial grade cubical freezer, 4 m on a side, has a composite wall consisting of an exterior sheet of 5.0-mm thick plain carbon steel (kst= 60.5 w/m k), an intermediate layer of 100-mm thick polyurethane insulation (kins 0.02 w/m k), and an inner sheet of 5.0- mm thick aluminium alloy (kal polyurethane insulation and both metallic sheets are each characterized by a thermal contact resistance of r 2.5 x 104 m2 k/w. (a) what is the steady-state cooling load that must be maintained by the refrigerator under conditions for which the outer and inner surface temperatures are 25°c and -5°c, respectively? (b) for power saving purpose, which wall material should be increased/reduced in. thickness in order to reduce 50% of the cooling load found in part (a)? redesign the thickness of the proposed material. 177 w/m-k). adhesive interfaces between the q=575.93 w
