Output Power and Voltage-Time Characteristics of Mono-Crystalline Photovoltaic Panel at Federal University of Agriculture, Abeokuta (FUNAAB), Alabata, Ogun State, Nigeria Under FUNAAB Weather

AbstractSolar energy is gaining more attention than ever before due to its potential ability to provide the world energy needed at a sufficient and reliable rate. Putting more focus on its optimum harvesting and utilization can eventually solve the problem of energy shortage by balancing up the energy demand of the nation. Adequate information on the output voltage of the solar panel to cope with the output current during the daytime is essential to be able to predict accurately the estim...

PERFORMANCE EVALUATION OF MONO-CRYSTALLINE PHOTOVOLTAIC PANELS IN FUNAAB, ALABATA, OGUN STATE, NIGERIA WEATHER CONDITION

AbstractThe current-voltage characteristic is the basic descriptor of photovoltaic device and is used to test the performance of PV panel. The manufacture specifications on solar panels are obtained under standard condition (solar irradiance of 1000 W/m2, AM 1.5 and operating temperature of 25oC) which is not the real operating condition the solar panels are exposed to on the installation site. With this, the information obtained from the manufacture specifications would not be sufficient ...

Development of a Solar Powered Poultry Egg Incubator for South West Nigeria

AbstractEgg incubators with regular, effective and efficient operation have the capacities of providing enough poultry birds which can serve every household in Nigeria with sufficient amount of protein on daily basis. Although many commercial incubators in Nigeria has folded up due to epileptic and erratic electricity supply which disrupts and impairs the operation of the incubators and reduce their level of performance resulting into low production and high cost of poultry birds. In order to...

Design of Distillation Column

Azeotropic distillation of ethanol-water mixture is accomplished by adding a volatile thirdcomponent to the liquid which changes the volatility of one of the two components more than theother so the components are separated by distillation. The two components to be separated oftenhave similar boiling point components which do or do not azeotrope in the binary mixture, butsometimes there are components which do azeotrope despite having vastly different boiling points.It is likely that in some ...

VAPOR–LIQUID EQUILIBRIA OF MIXTURES CONTAINING n-DECANE, CARBON DIOXIDE AND ARGON USING MOLECULAR SIMULATION TECHNIQUES (GIBBS ENSEMBLE MONTE CARLO SIMULATION)

 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 po...

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...

Shows the relationship  between the level of trader's education and enlightments determine how they utilize telecom services and futures available on the hand sets and service's provided by the Networks providers.

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...
