A manometer is an instrument for measuring the pressure acting on a column of fluid. The main types of manometers are U-tube, well type, and inclined.
Manometers can be used to record metabolic gas exchanges of any kind. Measurements of the gas exchange can be recorded using a respirometer as well.
Because they do not exist in this question.
from 400 manometers till 700-750 manometer.
By using a device called manometers.
the pressure whose pressure is to be calculated is flowing agaunst gravity
what is a manometer? and what is application of manometer in industrial? A Manometer is a device which can be used to measure pressure of fluids(i.e liquids and Gases). PRINCIPLE: Manometers are those pressure measuring devices which are based on the principle of balancing the column of liquid(whose pressure is to be found) by the same or another column of liquid. They are of two types 1. simple manometers 2.Differential manometers simple manometers are those which measure pressure at a point in a fluid containing in the pipe or a vessel. On the other hand Differential manometers measure the difference of pressure between any two points in a fluid contained in a pipe or vessel. Industrial applications: Pressure guages are used for a variety of industrial and application specific pressure monitering applications. visual monitering of air and gas pressure for compressors,Vaccum equipment and speciality tank applications such as medical gas cylinders, fire extinguishers,
A double tube manometer measure pressure. Manometers use liquid in a column and balance it against the pressure that they are measuring.
One of ends of the tube is used for pressure measurements, the other can be left open to the atmosphere to measure static pressure, or can be attached to the low end of a pressure system to measure differential pressure.
What is a two liquid well type manometer is one of the three main types of manometers. This type is best applied to reading scales that are properly calibrated and in the right units.
Mercury is a d-block element. It is the only metallic element which is a liquid at standard temperature and pressure. It is widely used in thermometers.Mercury is a metal element. It is used in thermometers,barometers and manometers. Also used to make some medicines and cosmetics.
Inverted U-tube manometer is used for measuring pressure differences in liquids. The space above the liquid in the manometer is filled with air which can be admitted or expelled through the tap on the top, in order to adjust the level of the liquid in the manometer.
