Which two instruments are used to measure?

Which two instruments are used to measure?

Tools used to measure length include a ruler, a Vernier caliper, and a micrometer screw gauge. To measure the diameter of objects, like pipe and wire, a vernier caliper and a micrometer screw gauge can be used.

What instrument is used to measure the pressure of a gas?

manometer
A manometer is an apparatus used to measure the pressure of a sample of a gas.

What instrument is used to measure wind direction?

Anemometers
Anemometers measure wind speed and determine wind direction. Using these sets of data, meteorologists can calculate wind pressure.

How do you measure wind pressure?

Calculate wind pressure. Wind pressure is given by the equation P = 0.00256 x V2, where V is the speed of the wind in miles per hour (mph). The unit for wind pressure is pounds per square foot (psf). For example, if the wind speed is 70 mph, the wind pressure is 0.00256 x 702 = 12.5 psf.

What is the instrument used to measure the air temperature?

thermometers
Air temperature is measured with thermometers. Common thermometers consist of a glass rod with a very thin tube in it. The tube contains a liquid that is supplied from a reservoir, or “bulb,” at the base of the thermometer. Sometimes the liquid is mercury, and sometimes it is red-colored alcohol.

What instruments measure area?

planimeter
A planimeter, also known as a platometer, is a measuring instrument used to determine the area of an arbitrary two-dimensional shape.

How is manometer pronounced?

Break ‘manometer’ down into sounds: [MUH] + [NOM] + [I] + [TUH] – say it out loud and exaggerate the sounds until you can consistently produce them.

Which device is used for measuring pressure of a gas liquid in a vessel?

A manometer is a device similar to a barometer that can be used to measure the pressure of a gas trapped in a container.

What is the instrument used to measure air pressure?

What instrument is used to measure air pressure? A barometer using mercury is common. The atmospheric pressure presses down on a reservoir of mercury and the mercury is forced up the tube a certain distance depending on the pressure. This is often recorded as mm H g or (rarely) inches Hg.

How is pressure measured in a lab?

This is often recorded as mm H g or (rarely) inches Hg. Our lab uses meters with a digital display to measure the pressure and I suspect that they use a method similar to an aneroid barometer which uses wafers that expand and contract with pressure changes to move an instrument.

How does a mercury barometer measure atmospheric pressure?

A barometer using mercury is common. The atmospheric pressure presses down on a reservoir of mercury and the mercury is forced up the tube a certain distance depending on the pressure. This is often recorded as mm H g or (rarely) inches Hg.
