In order for a computer to perform well, it is important to keep the central processing unit (CPU) cool, and this can be accomplished by using a liquid coolant. This study was conducted to investigate how effective nanofluids could be as a coolant for a water block used in CPU cooling. The nanofluids used in the experiment contained Al2O3 nanoparticles and SDS surfactant in a mixture in water at volume fractions of 0.5%. They were prepared using an ultrasonic cleaner, and then tested to determine how well they transferred heat and the amount of pump power needed. The findings suggest that nanofluids with higher concentrations have better convection coefficient values and are more efficient at reducing the temperature of the water block, but they require more pumping power. It was concluded that the Al2O3 nanofluid with SDS surfactant could be used as a coolant for CPU cooling because of its effectiveness in lowering the temperature of the water block. The present work results are agreed with data available in the literature.

MODELING WATER QUALITY INDEX USING GEOGRAPHIC INFORMATION SYSTEMS AND WEIGHTED ARITHMETIC INDEX IN KIRKUK, IRAQ

In this study, various water quality parameters have been selected and examined. Weighted Arithmetic Index (WAI) method used to calculate Water Quality Index (WQI). Besides, a statistical model for WQI prediction was proposed to test the correlation between WQI, Acidity (pH), Turbidity (T), Total Dissolved-Solids (TDS), Total Suspended-Solids (TSS), and Electricalconductivity (Ec). The study was conducted in Kirkuk, north of Iraq. The results of laboratory tests showed that the quality of drinking water that is processed from Kirkuk water project K1 is within the Iraqi specifications, except in one characteristic (Turbidity). The calculated WQI ranged between 67.37-109.92. Water Quality (WQ) was within good and poor water. For the predicted model, an accuracy value was calculated by the regression process. The obtained regression coefficient value R2 was equal to 0.99. The results demonstrated that the features obtained by regression analysis are able to predicate the WQI with very high accuracy.

The study displayed the heat transfer in a rectangular perforated fin plate by natural convection type, experiments produced through in an experimental facility designed and built a unique device for this study. And simulated with ANSYS program. The fins that used in this study including five types, the first one without perforated and the perforations were used with the remains fins by different shape as circular perforation these fins perforation by a different number of circles (1, 2, 4 and 8 circles) the cross-section area is same for all perforation’s fins (28.26 cm ) for all perforated fin. These perforations distributed on 1 circle have a 60 mm 2 diameter and after that divided to 2 circles have diameter 30 mm, the 2 circles also divided to 4 circles have diameter 15 mm and the last one has 8 circles with 7.5 mm diameter is produced from divided the 4 circles perforated fin. The experiment is processed for different power is ranged from (30, 60 and 90 W). The results for practical side shows the temperature drops along the length, the temperature dropped in non-perforated fin was (31.9-28°C) at 30 W but for perforated fin maximum drop was (31.9-27.5°C) for one circle perforated fin also observed the temperature drop at 60 W along the non-perforated fin was (86.6-76°C) but for perforated fin maximum drop was (86.6-74.3°C) at one circle perforated. The last one was at 90 W for non-perforated fin was (105.9-94.48°C) but for perforated fin was from (105.9-89.9°C).

In this study, by using the first and second law of thermodynamics the energy and exergy analyses have been applied to the Aliaga Gas turbines and combined power plant cycle. Depending on the power plant flow charts diagram the input and output points for each unites have been determined. The thermodynamic properties (e.g., temperature, pressure and mass flow rate) of the specified points momentarily were collected from the power plant cycle. By using these properties, the enthalpy, entropy and exergy quantity were calculated for each point in Engineering Equation Solver (EES) programs. The results of the study show that the efficiencies for the first and second laws of thermodynamics are found as 32.8 % and 43.4 % respectively. As a result; when the energy and exergy analyses were applied for each unit of the power plant, the maximum exergy destruction was in turn-combustion chamber, boiler, condenser; and the exergy destruction in other units was found to be very low. When reducing the exergy destruction in the power plant, its efficiency is expected to increase. The increased efficiency is parallel with energy cost decreased, and thus it will be occured the decline in harmful emissions released to the environment.
