Types Of Pressure
Q1: What is Pressure?
Answer:
The pressure is defined as the force applied on an object measured per unit area, i.e. the force applied per unit area of the object is called the pressure of the object.
Q2: What is Pressure Formula?
Answer:
The formula used to calculate the pressure applied on an object is,
P = F/A
where,
F is the force applied
A is the area of the surface on which force is applied
Q2: What is Unit and Dimension of Pressure?
Answer:
We can calculate the pressure applied on an object by taking the ratio of force applied to the surface area of the object. So the force is measured in kgms2. The SI unit to measure pressure is Pascal (Pa). The dimension of pressure is,[ML-1T-2]
Q3: What are Different Types of Pressure?
Answer:
The different types of pressure experienced by us,
- Absolute Pressure
- Gauge Pressure
- Differential Pressure
- Sealed Pressure or Vacuum Pressure
Q4: What is difference between Gauge Pressure and Differential Pressure?
Answer:
Differential Pressure is the difference between the two pressure while Gauge Pressure or Overpressure is defined as the difference between Absolute Pressure and Atmospheric Pressure.
Therefore, we can conclude that Gauge Pressure can be Differential Pressure but not vice-versa.
Q5: Why Straps Provided on School Bags are made Wider?
Answer:
The straps provided in the school bag are made wider so as to reduce the pressure exerted by the school bag on the shoulders of the children. As increasing the surface area of the straps reduces the pressure applied by the bag,
Pressure is inversely proportional to the surface area of the object.
P ∝ 1/A
Types of Pressure
Pressure is the force applied per unit area of an object. It is also called the per unit force on an Area. There are various types of pressure that we encounter in our daily life including atmospheric pressure, Gauge pressure, etc. Pressure is calculated by taking the ratio of the force applied to the surface area of the object.
In this article, pressure, its formula, its types, and others are in detail.
