Pressure and Its Measurement topics include: Pressure distribution in fluid, pressure measurement, pascals law and compression fluid pressure point.

In fluid mechanics, pressure is the force exerted on an area. The formula for calculating pressure is P = F/A, where F is force and A is area. 

Here are some types of pressure measurement:
Absolute pressure:
The total value of the force per unit area exerted by a fluid surface. Absolute pressure is the difference between the pressure at a given point in a fluid and total zero pressure or a perfect vacuum. Absolute pressure is measured with reference to the absolute zero in the pressure scale.
Gauge pressure: The pressure measured above atmospheric pressure. 

Different types of pressure measurement apparatus include: Barometers, Manometers, Mechanical gauges. 
A manometer is a pressure measuring device that balances a column of liquid with the same or another column of liquid. Manometers measure the pressure of liquid relative to an external source, which is usually the earth's atmosphere. 
Differential pressure is the difference in pressure between two points in a fluid system. 
Fluid pressure is measured in Pascals (Pa), where one Pascal is equal to one Newton per square meter (N/m2)
