Flow rates measure the movement and energy of liquids or gases through channels or tubes. Municipal water systems, manufacturing facilities, fire pumps, and agriculture use flow rates to ensure efficient and safe operations.
A flow rate has to do with the movement of a liquid or gas through some type of channel or tube. In addition to measuring the speed of movement, flow rates often include analysis of the amount of energy or work that is created as the substance moves forward. Measuring flow rates can help determine how effective different systems are at controlling the flow of a substance through a given channel or system.
Water flow rates are important in many contexts. Municipal water systems use measurements of this type to ensure that the pumps that move water through the canal network maintain an acceptable level of flow pressure. This in turn helps ensure that every fitting along the system receives a constant, adequate flow but not so high that it causes excessive wear within the channel piping or at various water leakage points. By regularly checking flow rates at strategic points along the system, the equipment used to maintain flow can be adjusted when and as needed.
Gas or air flow rates are also important in a number of contexts, including manufacturing facilities. By controlling the flow of pressurized air through a system, that pressure can be maintained at a level that allows workers to use the air hoses in cleaning manufacturing machinery. The same is true with systems that use a certain type of natural gas as a fuel type. Adjusting the airflow rates for such devices not only ensures that the equipment operates efficiently, but also that workers can use it safely.
Fire pumps are another example of equipment where flow measurement is very important. Maintaining the correct flow pressure is important in providing efficient water flow to deal with a burning building or similar situation. If the water pressure drops below acceptable levels, the water flow won’t be as strong and firefighters may have to move closer to the fire. This in turn puts individuals attempting to extinguish the fire at greater risk and could lead to further loss of life.
Flow rates are not always controlled with the use of pumps and equipment. In some applications, the idea is to observe the natural flow of water within a given environment. For example, agricultural experts will observe the flow rate of groundwater as it moves between different soil levels as a means of determining the rate of uptake by different types of soil compounds. This information is invaluable, as it helps determine whether the soil is capable of supporting various types of plant life, in terms of the soil’s ability to hold the moisture needed to nourish plants.
