Question

At sea level , the atmospheric pressure is 1.04×10pawer5 pa . Assuming g = 10ms-2 and density of air to be uniform and equal to 1.3 kg m-3, find the height of the atmosphere.

Open in App
Solution

Pressure = hdg

h = Pressure / (dg)
= (1.04 × 10^5 Pa) / (1.3 kg/m³ × 10 m/s²)
= 8000 m
= 8 kilometers

Height of the atmosphere is 8 kilometers
