To calculate the pressure it is important to know what pressure is. Pressure is a kind of force acting on a particular surface. In terms of quantity it is scalar in nature as it acts with a particular magnitude on the surface having the S.I. unit as Pascal.
- The formula for calculating pressure is : d*g*h
- where d= density of the fluid
- fluids can be defined as both liquids and gases
- g = gravity
- h= height
Given:
- d= 800kg/m3
- g= 10 m/2
- h= 10 cm = 0.1 m ( convert into meters by dividing it by 100 as all others are in meters)
Solution:
Pressure = 800*10*0.1
= 800 Pa
