Correct Answer is D) Flowmeter
Which of the following meters is not associated with viscosity
Explanation:
Viscosity is a property of fluids that measures the resistance of a fluid to flow. It is an important parameter in various industries, including oil and gas, pharmaceuticals, and food processing. Viscosity can be measured using various instruments, including viscometers and rheometers. In this article, we will discuss which of the following meters is not associated with viscosity.
Rotational viscometer
A rotational viscometer is a type of viscometer used to measure the viscosity of fluids. It operates by measuring the torque required to rotate a spindle immersed in a fluid at a constant speed. The viscosity of the fluid is proportional to the torque required to rotate the spindle. Rotational viscometers are commonly used in industries such as oil and gas, paints and coatings, and food processing.
Capillary viscometer
A capillary viscometer is another type of viscometer used to measure the viscosity of fluids. It operates by measuring the time required for a fluid to flow through a narrow capillary tube under the influence of gravity. The viscosity of the fluid is proportional to the time required for the fluid to flow through the tube. Capillary viscometers are commonly used in industries such as pharmaceuticals and chemicals.
Falling ball viscometer
A falling ball viscometer is a type of viscometer used to measure the viscosity of fluids. It operates by measuring the time required for a sphere to fall through a fluid under the influence of gravity. The viscosity of the fluid is proportional to the time required for the sphere to fall through the fluid. Falling ball viscometers are commonly used in industries such as petroleum and lubricants.
Flowmeter
A flowmeter is an instrument used to measure the rate of flow of a fluid in a pipeline or duct. It operates by measuring the velocity or volume of fluid passing through a sensor orifice. Flowmeters are commonly used in industries such as oil and gas, water treatment, and chemical processing.
Answer: Flowmeter
The flowmeter is not associated with viscosity. Although flowmeters measure the rate of flow of a fluid, they do not directly measure the viscosity of the fluid. The viscosity of a fluid can affect the accuracy of flowmeter measurements, but flowmeters are not designed to measure viscosity directly.
Conclusion
Viscosity is an essential property of fluids that affects various industrial processes. Rotational viscometers, capillary viscometers, and falling ball viscometers are commonly used to measure the viscosity of fluids. These instruments operate by measuring the torque, time, or velocity required for a fluid to flow under certain conditions. Flowmeters, on the other hand, are used to measure the rate of flow of a fluid in a pipeline or duct and are not directly associated with viscosity measurements. By understanding the different types of viscosity meters, industries can choose the most appropriate instrument for their specific applications and ensure accurate measurements of viscosity.
