VIBRATION MEASUREMENT AND PERFORMANCE EFFICIENCY OF GRASS MOWER
...Show More Authors

The experiment was conducted in field of the University of Baghdad, Jadryia region, Baghdad to measure vibration and performance efficiency of grass mower (machine cutting grass). Vibration in three axes are longitudinal X , lateral Y and vertical Z in four places of mower machine during cutting grass and Practical Productivity, Efficiency and Fuel Consumption measured in this experiment . Factorial design (3 x 2) used, mower speeds included 1.9 3.6 and 6.4 km/hr and engine load included idling and full load according to randomized complete design were used in this experiment. Least Significant Design (LSD) 0.05 was used to compare the mean of treatment. Result were showed that the mower speed 6.4 km/hr recorded high productivity (0.6557 ha/hr), low fuel consumption (1.62 l/ha), least efficiency ( 83.97 %), vibration values for three axes X,Y and Z (8.28, 7.85) and (5.35 m/sec²) for mower seat, (6.25, 7.05) and (4.80 m/sec²) for steering wheel and (14.78, 13.8) and (11.58 m/sec²) for mower chasses and (21.45, 20.05) and (16.15 m/sec²) for cover blades. Engine full load recorded high productivity (0.4080 ha/hr), efficiency (84.47%), and high vibration values for three axes X, Y and Z were (5.46, 5,03) and (3.56 m/sec²) for mower seat , (4.56, 5.30) and (3.36 m/sec²) for steering wheel, (13.30, 12.32) and (10.93 m/sec²) for mower chasses and (18.13, 17.03) and (13.83 m/sec²) for cover blades,Then these result a cross legislated permissible vibration exposure limits in the world.

Mechanical Properties of High Performance Concrete Containing Waste Plastic as Aggregate
...Show More Authors

         The world's population growth and the increasing demand for new infrastructure facilities and buildings , present us with the vision of a higher resources consumption, specially in the form of more durable concrete such as High Performance Concrete (HPC) . Moreover , the growth of the world pollution by plastic waste has been tremendous. The aim of this research is to investigate the change in mechanical properties of HPC with added waste plastics in concrete. For this purpose 2.5%, 5% and 7.5% in volume of natural fine aggregate in the HPC mixes were replaced by an equal volume of Polyethylene Terephthalate (PET) waste , got by shredded PET bottles. The mechanical propert

Absorber Diameter Effect on the Thermal Performance of Solar Steam Generator
...Show More Authors

In this work, a convex lens concentrating solar collector is designed and manufactured locally by using 10 convex lenses (concentrator) of a diameter 10cm and one Copper absorber tube of a diameter 12.5mm and 1mm in thickness 1m length. Two axes manual Tracking system also constructed to track the sun continuously in two directions. The experiments are made on 17th of May 2015 in climatic conditions of Baghdad. The experimental data are fed to a computer program to solve the thermal performing equation, to find efficiency and actual useful energy. Then this data is used in numerical CFD software for three different absorber diameters (12.5 mm, 18.75 mm and 25 mm). From the results that obtained the maximum the
