Question:

Pressure is determined as force per unit area of the surface. The SI unit of pressure, pascal is as shown below: 1Pa=1Nm⁻². If mass of air at sea level is 1034 gcm⁻², calculate the pressure in pascal.

Solution:

Pressure=weight per unit area=mg=1034g/cm²×1kg/1000g×(100cm/1m)²×9.80m/s²×1N/(kgm/s²)×1Pa/(1N/m²)=1.013×10⁵Pa
