Now a day the mostly air condition are use vapor compression refrigeration system in which R-22 refrigerant is used as a working substance. From the results of study it found that the quantity of water vapor or moisture in the air is condensed with in the fan coil unit while through out the evaporator. The fluid after condense is called condensed water. By this process the quantity of condensed water is increases when the air condition is used in the long time. To increase the utility the condensed water is recovered for the heart reduction in the finned-tube condenser. The experiment is consist of two conditions by using the air and condensed water to heart reduction. But in case of condensed water the pressure operation is controlled at 280 and 260 Psig respectively. The results of experiment shown the refrigeration effect coefficient of performance (C.O.P) and energy efficiency ratio (EER) is 39675 Btu/hr 3.01 and 10.3 Btu/hr.Watt respectively with the air is used. At the pressure operation 280 Psig refrigeration effect (C.O.P) and (EER) is 44212 Btu/hr 3.38 and 11.5 Btu/hr.Watt respectively and 49856 Btu/hr 3.99 and 13.6 Btu/hr.Watt at pressure operation 260 Psig. Furthermore the capacity of condenser is increases to 11.43% and 25.6% and also the refrigerant efficient is increases to 12.43% and 32.43% at the pressure operation 280 and 260 Psig. Thus the parameter of the energy efficiency ratio depends on the capacity of condenser working substance temperature (pressure operation) and air surrounding temperature.

This article describes an efficient approach to the implementation of bit-serial lattice wave digital filters based on field programmable gate array (FPGA). In this paper a time schedule of all of the bit-serial two-port adaptors is presented as a bridge between conception and completion. Finally with the satisfying frequency response the filter is successfully tested by both computer simulation and real signal measured from the programmed FPGA.

The objectives of this research were to develop of transmission line calculation program based on usage and frequency consisting of the two-wire transmission line twisted pair transmission line and coaxial transmission line. The program was developed in the form of graphical user interface in Malta. The developing and testing results found that the program was correctly capable to calculate capacity conductance inductance resistance and impedance for each transmission line usage and frequency. The results from the program with black box testing by five experts and twenty system users found the average and the standard deviation of results form computer experts were 4.04 and 0.36 respectively while those of results form the system users were 3.88 and 0.48 respectively. Conclusion it showed that the efficiency of the calculation program was a high level and can be used as a teaching and learning as well.

This Research is to Study the Development of 6k White Gold Alloys for Jewelry Production. By Studying the Influence of 6k White Gold Alloys on Physical Properties for Jewelry Molding Process. Of 6k Gold Alloys at Various Compound Rates. The Results of the Experiments Show that the Chemical Composition of 6k White Gold Alloys is Slightly Different when Compared with the XRF (X-ray Fluorescence Spectrometers). Compare the pre and Post-Melting Quantities. The Result of the Compounding Test with the Color Level of 6k White Gold at the Compound Rate 25%Au+54%Ag+0%Cu+3%Zn+18%Pd The Lowest Color Level was L * = 82.14 a * = -0.16 b * = 7.71 and the Lowest Color Difference was 21.07. With other Ingredients It Shows that the Test Specimen of 6k White Gold has a Rather Greenish Color and is Slightly Yellowish Compared to the Blue Line that Approaches the Standard line. These Properties are the Physical Properties Required to Produce a 6k White Gold Jewelry Body.

This Research is to Study the Development of 6k White Gold Alloys for Jewelry Production.The Optimum Conditions for Casting Jewelry and Jewelry were Investigated. The Results of the Experiments Show that the Chemical Composition of the 6k White Gold Alloys is Slightly Different when Compared with XRF (X-ray Fluorescence Spectrometers) Pre-and Post-Melting Quantities The Heat of the Test Specimen was found to be 5%Au+42%Ag+12%Cu+3%Zn+18%Pd 25%Au+46%Ag+8%Cu+3%Zn+ 18%Pd 25%Au+50%Ag+4% Cu+3% Zn+18% Pd and 25%Au+54%Ag+0%Cu+3%Zn+ 18%Pd It is Found that the Heat from the Beginning to the Level of Change before the Liquid is used the Average Temperature of 702.3 - 636.7 Degrees Celsius Respectively 25%Au+54%Ag+0%Cu+3%Zn+18%Pd It is the Formula that Gives the Lowest Value of Liquid State Change from 636.7 Degrees Celsius to the Best Value of this Experiment. Suitable for use in the Manufacture of Jewelry due to its Melting Ability for Molding. Melting for Molding and Formed by Hand. The Amount of Zinc(Zn) may be an Important Factor in the Variation which is Directly Proportional to the Maximum Increase in the Final order of 3.58 Percent.
