An earthen dam is constructed on an impermeable bedrock layer. it is 123 m across (i. e., the distance from the water in the reservoir to the tailwaters below the dam is 123 m). the average hydraulic conductivity of the material used in the dam construction is 1.33 ml d. the water in the reservoir behind the dam is 18.5 m deep and the tailwaters below the dam are 4.6 m deep. compute the volume of water that seeps from the reservoir, through the dam, and into the tailwaters per 100-m-wide strip of the dam in cubic meters per day. fetter, c. w.. applied hydrogeology (p. 149). waveland press, inc.. kindle edition.

Air is compressed isentropically from an initial state of 300 k and 101 kpa to a final temperature of 1000 k. determine the final pressure using the following approaches: (a) approximate analysis (using properties at the average temperature) (b) exact analysis

Asteel wire of 2 mm diameter is fixed between two points located 2 m apart. the tensile force in the wire is 250n, if its density of steel is given by 7830 kg/m3 the fundamental frequency of vibration hz? ?

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
