Measuring Stream Discharge Using The Float Method A Simple Yet Briefly put, this method involves measuring the surface velocity of the water with a floating object, and then multiplying this velocity by the width and average depth of the channel. below is a form you can use to perform the calculations automatically, and below that are step by step instructions. A common but simple method for measuring flow rate through an open channel is the float method. although not as accurate as a measuring device such as a flume or a velocity probe, the.
Flow Measurements Iit Roorkee Pdf Flow Measurement Fluid Dynamics Calculate the flow of the stream during your release day event. This document provides instructions for measuring open channel flow using the float method. it describes the necessary equipment, including a tape measure, stopwatch, depth measuring device, and floating objects. Learn how to measure stream discharge using the float method. step by step guide, equipment list, and formulas included. Stream flow can be determined by measuring the velocity of water and the cross sectional area of the stream. the formula to use when calculating stream flow is: to measure velocity a float (orange peel) will be used to determine how fast the water is flowing.

Stream flow can be determined by measuring the velocity of water and the cross sectional area of the stream. the formula to use when calculating stream flow is: to measure velocity a float (orange peel) will be used to determine how fast the water is flowing. Float method – this method measures surface velocity. mean velocity is obtained using a correction factor. the basic idea is to measure the time that it takes the object to float a specified distance downstream. Locate a relatively straight reach of stream to conduct the measurement. ideally this will be 100 feet long, but as short as 15 feet is acceptable if it is the only option. stretch a tape measure across the channel at the downstream end of the reach. this should be perpendicular to the channel. 6.2 experiment 6.2.1 principle precise discharge measurement leads to efficient utilization of scarce water resource. Drop a leaf in the water flow of the stream you want to measure. walk in the direction the leaf is floating at a normal pace for about 30 metres or 35 paces. see how far the leaf floats during the time you are walking and estimate the water flow as shown in the examples.
