Quality load cycling

The polymeric tlbial components were coated with pure aluminium, some lOoX thick in a vacuum evaporation unit to improve the quality of the holographs. This film was removed in Isopropyl alcohol before each wear test. Holographs of the unworn and worn tlbial components were assessed and the volume of material removed (V) in a known period was estimated by simple geometrical procedures. The loading cycle enabled ( PdX) to be evaluated and an equivalent wear factor (k) was calculated from the relationship. 

In application areas 2 4 the display cells are mechanical loaded on purpose. In the second application area it is loaded once when bending the cell in its final shape. Areas 3 and 4 require more loading cycles. Not only functional requirements on the display performance (the image quality), but also structural requirements on the display construction and the materials are needed. 

Determine the COP, horsepower required, and cooling load of a Carnot vapor refrigeration cycle using R-12 as the working fluid and in which the condenser temperature is 100°F and the evaporation temperature is 20°F. The circulation rate of fluid is O.llbm/sec. Determine the compressor power required, turbine power produced, net power required, cooling load, quality at the inlet of the evaporator, quality at the inlet of the compressor, and COP of the refrigerator.
