Azeotropic distillation of ethanol-water mixture is accomplished by adding a volatile third component to the liquid which changes the volatility of one of the two components more than the other so the components are separated by distillation. The two components to be separated often have similar boiling point components which do or do not azeotrope in the binary mixture, but sometimes there are components which do azeotrope despite having vastly different boiling points. It is likely that in ...
Abstract The CO2–hydrocarbons systems is common in oil and gas industry as a geological fluid. CO2 plays a vital role in biological processes namely photosynthesis, respiration, and actively participates in the carbon cycle. However, the time gradient of carbon dioxide concentration in the atmosphere has become a major global concern. The environmental challenges associated with the control and management of anthropogenic emissions of greenhouse gases have been the focal point of soci...
This project study was aimed at designing, fabricating, and evaluating the performance of a double effect evaporator, which was used to evaporate sugar syrup to be used for students’ demonstration. During the course of the study, the methods that were used comprised of the material balances, energy balances, and determination of the component parts of the evaporator. The results from the study included the overall material in the evaporator’s system, the material balance for each effect, ...
ABSTRACT The sandcrete blocks have been a major material for the construction of structures in Nigeria. This material have provided a means of constructing walls and partition. However, the sandcrete blocks also have the disadvantage of cost and unavailability of materials such as granite, cement and other combining aggregates. Laterite, a readily available material can be efficiently used to produce Laterite bricks which can be fired to improve it's mechanical and physical property. The inc...

One of the most critical inputs to vegetable (fruits) production in semi-arid areas, dry season farming and nursery establishment is water. During the dry season or off season, the source of water for vegetable growing is from irrigation while in the wet season, rainfall is the source of water. Young vegetable seedlings in the nursery or in the field should be watered in the early morning or in the evening. Watering should be done before transplanting particularly in the evening. Over-wa...
This experiment was conducted in order to have a broader knowledge on hydraulic jump and its applications. It was performed in the hydraulic laboratory of the department of Water Resources and Environmental Engineering, Ahmadu Bello University, Zaria, using the TQH23, 2.52m flow rectangular channel and the HID hydraulic bench which provides water to the channel with the aid of the pump incorporated in the HID. Five different discharges were obtained by varying the flow. Hydraulic jump...
ABSTRACT Power inverter is an electrical appliance that can be used with DC battery as an alternativesource of energy supply in the event of power failures and energy crisis. It is cheap, clean,very conducive and silent when in operation and a very reliable source of power supply as togenerator. Modern research and technologies have shown that inverter is one of the cheapestforms of energy generation. Throughout the world, it is readily available and can be partnerto solar energy particularly...
BSTRACT Automatic door control is becoming popular due to its numerous benefits. Automatic door control refers to the control of doors and domestic features by just sensing the present of human being at door and automatically open the door with the persons interface or by remote control. Artificial Intelligence provides us the framework to go real-time decision and automation for Internet of Things (IoT). The work deals with discussion about different intelligent home automation systems and t...
This work is on design and Construction of Automated door security system with GSM notification. Is an electrical Electronics Engineering Project.
ABSTRACT This project presents a design and implementation of new advanced Securitypower control using Android power switch system that uses WiFi technology as anetwork infrastructure connecting its parts. The proposed system consists of twomain components; the first part is the server (web server), which presents systemcore that manages, controls, and monitors users’ home. Users and systemadministrator can locally (LAN) or remotely (internet) manages and control systemcode. Second part is ...
The demand for EN8 mild steel in the industry is high due to its integral mechanical properties. However, conventional machining of EN8 mild steel is a challenging task. In this research work, prediction and optimization of EN8 mild steel Material Removal Rate (MRR) and Surface Roughness (Ra) using Response Surface Methodology (R.S. M) were investigated. The dimension of the EN8 mild steel material was 0.12 m diameter and 0.08 m in length. The turning operation of the ENS mild steel was carri...
The physical characteristics and combustion performance of briquettes produced from four lignocellulosic materials and its admixtures using a 5-ton HBP with a rectangular mould had been carried out. The sole materials evaluated include sawdust, waste paper, cow dung and rice bran and its admixtures in the following proportions: Sawdust: paper (2:1), rice barn: paper (2:1), cow dung: paper (2:1), Rice bran: sawdust: paper (1:1:1) investigating the bonding properties of paper. The result show...
Ergonomic studies were carried out on selected shoulder-strap brush cutters to evaluate some deficient ergonomic factors associated with their operations. These deficiencies were used as basis for modification. Contextual interview and field interactions were used to obtain ergonomic data that are descriptively analyzed. Results of ergonomic assessment shows that operators are subjected to pains around the neck, shoulders, upper arm and fingers which are largely traceable to shoulder-strap-lo...
The performance evaluation of a dual-function device for slicing and drying Okra developed at the Federal College of Agriculture, Ishiagu Nigeria was carried out and reported. The device was designed to slice and dry okra in one single-sequence operation. To evaluate the devices, some physical characteristics (the axial length, mean equivalent diameters and sphericity) of okra samples were measured to determine blade distance and other machine considerations. The results showed that the...
