Given: The size of the insulated pipe for transporting hot water is to be minimized. The size of the insulated pipe can be expressed as, y = D + 2T, where D is the diameter of the pipe, T is the insulation thickness, The total annual operating cost consists of the sum of the pumping cost and the heating cost, and it is to be no more than $40,000. Pumping cost = 8/D5 Heating cost = 1500/T Find: (a) the objective function and the constraint (b) the minimum cost using the hemstitching method, start with D = 0.2 and T = 0.1, and with ΔD = 0.005.

Problem #3 (15 points) A pipe carrying high-temperature water is to be insulated and then mounted in a restricted space as shown in the figure below. The choices of the pipe diameter D (in meters) and the insulation X (in meters) are to be such that the outside diameter of the insulation Y is a minimum, but the total operating cost of the installation is limited to $40,000. This annual operating cost has two components, the water pumping power cost...

5. Hot water at 50 C is routed from one building in which it is generated to an adjoining building in which it is used for space heating. Transfer between the buildings occurs in a steel pipe (k -60 W/mK) of 100-mm outside diameter and 8-mm wall thickness. During the winter, representative environmental conditions involve air at T=-5 C and V= 3 m/s in cross flow over the pipe (a) If the cost of producing the hot water is $0.10...

For example, for specimens incorporating air spaces or stud spaces, the metering area shall span an integral number of spaces (see 5.5). The depth of...
