How to Measure Flow of Water in Open Channels? | Water Engineering

The different methods available for measuring water in open channels may be grouped as: 1. Velocity-area methods, and 2. Direct discharge methods. 1. Velocity-Area Methods: In these methods the velocity of flow in the channel is measured by some means and the discharge is calculated from the velocity and the area of cross-section by using Q=AV. The common methods for [...]

How to Measure Flow of Water in Pipes? | Water Engineering

Several methods are available for measuring flow in pipes. Only a few of them which can be used on the farm are discussed here: 1. Volumetric Measurements: Flow measurements by this method are made by measuring the time required for the flow to fill a container of known volume. Volume divided by time is equal to the rate of flow. [...]

How to Determine Capacity of a Storage Reservoir? | Water Engineering

The capacity of a storage reservoir is determined on the basis of the inflow to the reservoir and the demand of the consumers (or the yield of the reservoir). The following two methods are generally used for determining the capacity of a storage reservoir: 1. Analytical Method: In this method an analysis of demand and inflow of water per month [...]

Analysis of Water: Physical, Chemical & Bacteriological | Water Engineering

The analysis of water involves the various tests to be carried out for determining the impurities which may be present in water. The following three types of analyses are carried out for water: (1) Physical Analysis: The physical analysis of water involves the physical tests which are carried out to determine the physical impurities and the corresponding physical character­istics of [...]

List of 4 Commonly Used Turbidimeters | Instruments | Water Engineering

The commonly used turbidimeters are as indicated below: 1. Jackson Turbidimeter (or Jackson Candle Turbidimeter): It consists of a graduated glass rube placed in a metal cylindrical container which is supported on a metal stand. At the bottom of the stand a standard candle of bees wax is fixed. The candle is so designed that it burns within the limits [...]

How to Detect the Presence of Bacteria in Water? | Water Engineering

For detecting the presence of bacteria of coliform group and measuring their concentration in water the following methods are adopted: I. Total Count or Agar Plate Count Test: In this lest, bacteria are cultivated on specially prepared medium of agar for different dilutions of sample of water with sterilised/distilled water. The dilutions commonly used are 1/10, 1/100 etc. The diluted [...]

How to Remove Colour, Odour and Taste from Water? | Water Engineering

In this article we will discuss about how to remove colour, odour and taste from water. Aeration: Aeration is a process in which water is brought in intimate contact with atmospheric air to promote exchange of gases between water and atmospheric air. The aeration of water serves the following purposes: (i) In the course of aeration, oxygen from atmospheric air [...]

Well: Interference and Flow | Groundwater | Water Engineering

In this article we will discuss about interference among wells and flow in a well. Interference among Wells: If two or more wells are located so close to each other that when they are discharging their drawdown curves intersect then one well is said to interfere with the other. Observations indicate that due to the interference of wells the discharge [...]
