Atank with some water in it begins to drain. the function v ( t ) = 46 − 1.5 t determines the volume of the water in the tank (in gallons) given a number of minutes t since the water began draining. what is the vertical intercept of f ? what does your answer to part (a) represent? select all that apply. how many minutes it takes for all of the water to drain from the tank. the number of gallons of water in the tank when it starts draining. the weight of the tank when it is empty. list all horizontal intercepts (or "roots") of f . what does your answer to part (b) represent? select all that apply. the weight of the tank when it is empty. how many minutes it takes for all of the water to drain from the tank. the number of gallons of water in the tank when it starts draining.

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
