WebSelect the appropriate DC fan to supply 400 LFM (2 m/s) airflow into a 4 inch (102 mm) diameter circular duct with a pressure drop of 0.1 inches of water (25 Pa). Using the airflow calculator above, type the airflow value of 400 and select LFM as the units. Next type the circular duct dimensions of r = 2 in. After pressing the Calculate Airflow button, read the … WebThe use of a steam flowmeter may be used to directly measure the steam usage of an operational item of plant. This may be used to monitor the results of energy saving schemes and to compare the efficiency of one item of plant with another. The steam can then be costed as a raw material at any stage of the production process, so that the cost of ...

WebMay 3, 2024 · Gas Mass Flow Measurement. Flow measurement is the measure of bulk fluid movement and is determined through: Positive displacement meters collect a fixed … Flow measurement is the quantification of bulk fluid movement. Flow can be measured using devices called flowmeters in various ways. The common types of flowmeters with industrial applications are listed below: Obstruction type (differential pressure or variable area)Inferential (turbine … See more Both gas and liquid flow can be measured in physical quantities of kind volumetric or mass flow rates, with units such as liters per second or kilograms per second, respectively. These measurements are related by the … See more A primary flow element is a device inserted into the flowing fluid that produces a physical property that can be accurately related to flow. For example, an orifice plate produces a … See more There are several types of flowmeter that rely on Bernoulli's principle. The pressure is measured either by using laminar plates, an orifice, a nozzle, or a Venturi tube to create an artificial constriction and then measure the pressure loss of fluids as they pass that … See more Optical flowmeters use light to determine flow rate. Small particles which accompany natural and industrial gases pass through two … See more A positive displacement meter may be compared to a bucket and a stopwatch. The stopwatch is started when the flow starts and stopped when the bucket reaches its limit. … See more A "variable area meter" measures fluid flow by allowing the cross sectional area of the device to vary in response to the flow, causing some measurable effect that indicates the rate. A rotameter is an example of a variable area meter, where a weighted "float" … See more Open channel flow describes cases where flowing liquid has a top surface open to the air; the cross-section of the flow is only determined by the shape of the channel on the lower side, and … See more WebThe volume flow rate Q Q of a fluid is defined to be the volume of fluid that is passing through a given cross sectional area per unit time.
