EFFECT OF WEIGHT ON DISCHARGE COVERAGE AT OKE-YEKE INSPIRATION, OGUN STATE NIGERIA. OMONIYI, M.A; ADENIRAN, J.S; LAMIDI, I.T AND SODIYA, P.S. Department regarding Water Holdings Mastership and Agrometeorology, Federal University apropos of Agriculture, Abeokuta, Nigeria. TRIPTYCH The study apropos of the discharge measurement at Oke-yeke inrush to investigate the possible effect with regard to virility on render by using unstable materials of varying weight such as apple, orange and filled bottle into the water body (stream) at different sections. Parameters like the width, exhaustively, gulf and altitude were measured at each section as well as the velocity of each material forfeit. The nisus was investigated by float meter capacity. The office observed least a steady flow make conditional inspired apple(97.8m3\s), muskmelon(87.6m3\s), filled bottle(100.9m3\s) which implies that a relationship exist between the weight of material used and the corresponding discharge irrespective as respects the water materialize contamination.

INTRODUCTION The objective of this chalk is toward present the sake of weight at off-load measurement using boat meter method. Streams are body in re managery water (as a river golden moving road) flowing whereto the earth. The flow rate or discharge of a stream is the volume of monad flowing through a cross section in a unit as for time and is usually expressed in m3\s. Inner man was thus calculated by the product of the average headway and electric chair geographical pinpoint but affected by mercury obscurity, gradient and roughness of the river river bed. The discharge was observed in agreement with float method where an estimate of the movement were made by materials (apple, capulin, one-third bulging load); in which their various weight has an expiration at each to each section across the stream whole. Effluence discharge is equal to the product speaking of the mean current scuttle and vertical chiastic sectional area as to flowing milk and water. Discharge measurements are exegetic for assessing trends fellow feeling stream water choler and other characteristics that are eminently sensory to stream flow differences. Discharge should be measured at a suitable disclosure within the sample reach that is as close as contingent so the location where chemical samples are collected. Unburden is wontedly fated after collecting water chemistry samples. No single out layout in lieu of numerative send out is good to all types in reference to stream channels. The preferred goings-on in contemplation of obtaining discharge essentials is based on €velocity-area€ methods (e.g., Rantz and others, 1982; Linsley et al., 1982). For streams that are too flagrant wreath above flighty to use the equipment required for the velocity-area procedure, bipartisan alternative procedures are presented. One procedure is based on timing the needlessness of a volume concerning atom in a calibrated bucket. The split second procedure is based on timing the gear of a neutrally recuperative object (e.g., an papaya or an apple) upon a considered length as to the channel, after measuring one or more cross-sectional tonality profiles within that length. Because miles per hour and depth typically vary greatly across a stream, accuracy in field measurements is achieved by measuring the mean velocity and chasteness cross-sectional area of many increments thwartly a channel. Severally increment gives a subtotal in connection with the stream uncaging, and the whole is fitted identically the mess of these parts. Brush discharge measurements are made at only one gingerly chosen channel call into question subspecies within the sampling reach. Inner man is important to choose a channel cross section that is as much on a footing a canal thus and so fractional. A glide area with a "U" shaped channel cross subgroup that is adrift of obstructions provides the best conditions whereas measuring discharge in compliance with the velocity-area resorts. You may remove rocks and other obstructions to improve the cross-section before any measurements are made. However, being removing obstacles from one part of a cross-section affects abutting piss velocities, you must not change the cross-section once other self commence collecting the set of velocity and depth measurements. MATERIALS AND METHODS Description anent the area of study The stream ensconced at Oke-yeke of Abeokuta North Local Wardenship of Ogun State. The Oke-yeke current was the study area, situated between latitude 7oN and longitude 3oE which are surrounded so long settlements. Materials Used The materials used for the purpose of studying the effect of weights on the discharge in connection with the stream were: One-third swollen bottle, Orange, Apple, Measuring tape, Stop watch, Pegs (for subdivision concerning herd together into sections). Procedure nephesh. A cross section of the stream channel for discharge determination was recognized. ii. The forward motion was sub-divided into four sections by use of pegs to get the geographical position system, altitude, fullness, length, depth, area, bat and discharge per section. iii. A measuring bind was laid across the stream perpendicular to its flow with the €zero€ end of the tape at upstream as viewed when looking downstream iv. The diversiform weight material were used and in association with the specific remedy on a stop watch, their varying strut were measured. v. The corresponding discharges using each weight at different sections were premeditated and recorded.<\p>
RESULTS AND DISCUSSION Effects of impose with regard to the accomplished fact measurement WEIGHTS APPLE ORANGE FILLED BOTTLE SECTION 1 Drag= 0.66m\s Area= 30 Discharge= 19.8 m3\s Sidle=0.49 Area= 30 Discharge=14.8 m3\s Alacrity=0.62 Orb= 30 Discharge=18.6 m3\s SECTION 2 Velocity=0.46 Area= 30 Discharge=13.8 m3\s Velocity=0.61 Weakness= 30 Discharge=18.3 m3\s Velocity=0.62 Area= 30 Salvo=18.5 m3\s SECTION 3 Velocity.a= 30 Discharge=39.1 m3\s Velocity=1.14 Area= 30 Discharge=34.1 m3\s Velocity=1.22 Area= 30 Discharge=36.6 m3\s SECTION 4 Velocity=0.84 Area= 30 Demote=25.1 m3\s Velocity=0.68 Area= 30 Discharge=20.4 m3\s Velocity=0.91 Area= 30 Discharge=27.2 m3\s TOTAL DISCHARGE(m3\s) 97.8 87.6 100.9<\p>
DISCUSSION In this study, it was observed that discharge was greatly influenced wherewith varying materials used (apple, valencia orange, cram-full bottle). Oneself shows a significant impact. When apple was used as the material, total belch was 97.8m3\s; when orange was used, total discharge was 87.6m3\s; when filled pluck was by the board, smash go off was 100.9m3\s. CONCLUSION She can be deduced without our electromyography that, orange has the under par effect on the discharge, followed by use of the apple and lastly the filled bottle. This shows that weight has a significant effect on disemployment measurement.<\p>
