Pressure

• Pressure can be calculated using the formula P = F/A, where P is pressure, F is force, and A is area.
• The SI unit of pressure is the pascal (Pa).
• pressure can be calculated using the formula P=F/A where F is the force and A is the surface area
• Pressure is defined as the amount of force that acts over a given area
• Pressure is the amount of force applied to an area.
• SI unit of pressure is N/m^2 or pascal(Pa) named after the scientist Blaise Pascal
• 1 pascal is the pressure exerted by a force of 1N on a surface area of 1m2 i.e.

  1 Pa = 1N/1m2
• The bigger unit of pressure is kilopascals (kPa)

  1 kPa = 1000 Pa
• If thrust is measured in kgf and area in cm2, then pressure is expressed in unit kgf cm-2
• 1 atm = 76 cm of mercury column

  = 1.013 x 10^5 Pa
