In this paper, a system of equations for the heat transfer of flat solar collectors (vertical plates) in a free air flow was solved. As a test example, all possible sizes of collectors were used, while the prototype was tested within 3-8% relative to the standardized standard deviation. Thermal characteristics decrease almost linearly as the distance between the pipes increases. This highlights the difficulty of transferring heat to the pipe from relatively long distances. This indicates the fact that a higher saturation of the tube per square unit (or length) of the absorbing plate increases
Plastic waste has been a global concern to overcome as it causes buildup and environmental issues. Potential lies in plastic waste which mainly consists of Polyolefin Plastic. Pyrolysis, thermal degradation under an inert atmosphere, technology commonly used in converting polyolefin plastic into useful products such as aromatic hydrocarbons. Over the years pyrolysis use several types of reactors where fluidized bed reactor holds major interest as of late. High heat transfer and fewer side reactions are one of the advantages of using a fluidized bed reactor. A review of fluidized bed reactor an
Mishrif Formation is regarded as the primary reservoir in the selected oil field. It is subdivided into three main units M1, L1, and L2. Based on 107 wells data, the static model construction is the crucial first stage to constructing a dynamic model for any reservoir, and it is here that the significance of this work becomes evident. The primary objective of this paper was to identify the distribution of petrophysical properties throughout the Mishrif reservoir and the initial oil-in-place calculation to assess the viability of working on reservoir modeling and the detection and resolution of
Kaolin clay sample from the Ordovician, Hiswah Formation in south Jordan, was used for faujasite synthesis. The process involved hydrothermal reactions after fusion with NaOH. The optimized conditions of faujasite crystallization were found to be at temperature of 700˚C, and time span between 72 h and 96 h. Faujasite began to crystallize from the kaolin after 48 h, and crystallization progressed with increasing time. The synthetic product has been characterized by X-ray diffraction (XRD), X-ray fluorescence (XRF), scanning electron microscope (SEM), and thermo-gravimetric (DTA/TGA) analysis.
Rainfall analysis is crucial to understanding precipitation patterns and their impacts on natural and human systems, such as agriculture, water resources management, and disaster preparedness and response. In this study, decadal rainfall patterns in Somalia were analyzed using the CHIRPS satellite precipitation dataset due to limited ground station data. The CHIRPS dataset provides gauge observations at different temporal resolutions, satellite estimates, and global climatology. Advanced statistical methods, including Excel and R, were used to analyze the precipitation data, and time series pl
