Design, Fabrication, and Performance Evaluation of a Double Effect Evaporator

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, ...

Analysis Of The Effect Of Polypropylene Polymer (Crushed Plastic Waste) On Oven Dried Laterite Bricks

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. Th...

DISCUSSION ON THE CROP WATER REQUIREMENT, PERIOD OF PLANTING, DAYS TO HARVEST (DEVELOPMENTAL STAGE) AND AREAS PLANTED OF THE FOLLOWING VEGETABLE (FRUIT) CROPS: TOMATO, ONION, OKRA, PEPPER

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&n...

STUDY OF HYDRAULIC JUMP IN A RECTANGULAR FLUME BY COMPARING RECTANGULAR BLOCK WIER AND SLUICE GATE

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. Hyd...

Design and Construction of a Power Inverter

ABSTRACTPower 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 ...

DESIGN AND CONSTRUCTION OF A MICROCONTROLLER BASED PREPARED ENERGY METER

BSTRACTAutomatic door control is becoming popular due to its numerous benefits. Automaticdoor control refers to the control of doors and domestic features by just sensing thepresent of human being at door and automatically open the door with the personsinterface or by remote control. Artificial Intelligence provides us the framework to goreal-time decision and automation for Internet of Things (IoT). The work deals withdiscussion about different intelligent home automation systems and techn...

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...

PREDICTION AND OPTIMIZATION OF EN8 MILD STEEL MATERIAL

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...

Characterization of briquettes produced from four lignocellulosic material admixtures using a hydraulic briquetting press (HBP)

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 ...

Ergonomic modification and performance evaluation of a shoulder-strapped brush cutter

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 shoulde...

Modification and performance evaluation of a dual-function okra processing device

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 ...

Performance evaluation of three coconut cracking devices and comparison with conventional cracking technique

Performance of three coconut cracking devices; punch-split, impact-split, hydraulic-split were carried out and their comparison with conventional (hand cracking technique) evaluated. Each cracking technique was evaluated for capacity, efficiency, ergonomics, and time required to crack a unit of different coconut grades.  The results showed that the average cracking efficiency for punch-split was 87.09 percent with a range of 86.76 to 95.00 percent, impact-split efficiency vari...
