Define pressure and atmospheric pressure and gauge pressure and absolute pressure
Answers
Answer:
The answer is given below
Explanation:
Gauge pressure- It is the amount of by which the pressure measured in a fluid or liquid exceeds that of the atmosphere.
Absolute pressure-It is measured relative to a full vacuum,so it is equal to gauge pressure plus the atmospheric pressure.
Atmospheric pressure-The pressure exerted by the weight of the atmosphere.
Pressure-It is the force applied perpendicular to the surface of object per unit area over which the force is distributed.
Answer: The answer lies in the explaination.
Explanation:
Okay, first of all, what is pressure?
Pressure is defined as force per unit area. The SI unit of pressure is Pascal ( Pa ).
Pressure (in Pa) = Force (in Newton (N))/Area (in m²)
Atmospheric pressure?
Atmospheric pressure is defined as the weight of the air column above an object. Atmospheric pressure is measured with the help of an instrument known as a barometer. The atmospheric pressure at sea level is 100k Pa and the weight of the air above is 250kg.
Absolute pressure?
Absolute pressure is defined as the pressure of a fluid in a vaccum.
Gauge pressure?
Gauge pressure refers to the pressure exerted by a fluid when in contact with air thus, under air/atmospheric pressure
