What is unit of flow?
Flow, or volumetric flow rate, is simply the volume of fluid that passes per unit of time. In water resources, flow is often measured in units of cubic feet per second (cfs), cubic meters per second (cms), gallons per minute (gpm), millions of gallons per day (MGD), or other various units.
How do we measure the flow rate of liquid Mcq?
The flow rate is measured with an orifice plate (d = 1.034) and pipe taps are used. At full flow rate, a differential pressure of 50 inches of water is produced.
Which device from following is used to control the flow rate?
A venturimeter is a device that is used for measuring the rate flow of a fluid flowing throughout the pipe. Was this answer helpful?
Which of the following represents the correct relation between flow rate and area of pipe?
8. Which of the following represents the correct relation between flow rate and area of pipe? Explanation: Flow rate and area of cross section of pipe are directly proportional. That is when the area of pipe is increased flow rate also increases.
Which of the following is correct for AC and DC tachometer?
Which of the following is correct for AC and DC tachometers? Explanation: For AC tachometer it has a sensitivity which is very less than the sensitivity of DC tachometers.
Is used to measure liquid flow Mcq?
Hence, coriolis method is used for the measuring liquid flow rate. Explanation: Orifice plate, venture tube and flow nozzle all these devices are used for flow obstruction.
Which type of level sensor is used in milk industry Mcq?
Explanation: The pneumatic level indicator measures the static pressure represented by the head of liquid in the tank.
Which protocol is used by proximity sensor?
standard I2C
Which type of position can be determined by a position sensor?
1. Which type of position can be determined by a position sensor? Explanation: Position sensors are capable of determining mechanical position of an object with respect to an arbitrary reference point. In addition, these sensors are also capable of detecting the presence of an object nearby.
Which of the following is used in level measurement?
Explanation: Float elements are used for measuring the liquid level of a system. Liquid level indication is obtained using displacement of float element. 2.
What is rotameter used to measure?
A rotameter (variable area meter) is a flow meter that measures volumetric flow of liquids and gases. The technique for measuring flow is accomplished by a freely moving float finding equilibrium in a tapered tube. The flow rate is then read from either a scale next to the tube or a scale on the tube.
What are the two methods of level measurement?
Level measurements are classified into two types– direct and indirect level measurements or performed by contact or non-contact transmitters. Direct level measurements are considered ideal for small level changes, which are observed in various industrial tanks.
What is the difference between direct and indirect measurement?
‘Direct measurement’ refers to measuring exactly the thing that you are looking to measure, while ‘indirect measurement’ means that you’re measuring something by measuring something else. This would be an example where I have to measure something ‘indirectly.
What is direct measurement with example?
Direct measures are those that measure student learning by assessing actual samples of student work. Examples include: exams/tests, papers, projects, presentations, portfolios, performances, etc.
What is a comparison measurement?
A device that compares the unknown length with the standard. Such measurement is known as comparison measurement and the instrument, which provides such a comparison, is known as Comparator. Comparators are generally used for linear measurements.
