Question

Using the fact that hydrogen gas consister of diatomic molecules with M = 2 kg//K - mol. Find the speed of sound in hydrogen at 27^(@) C .

Answer 1

Thus the speed of sound at 27°C temperature is V = 1321 m/s

Explanation:

Given data:

Mass of diatomic molecules of hydrogen gas "M" = 2 kg//K - mol

Temperature "T" = 27°C = 273 + 27 = 300 K

γ = 1.4

Solution:

V = √γ R T / M

V = √ 1.4 x 8.31 x 300 / 2 x 10^-3

V = 1321 m/s

Thus the speed of sound at 27°C temperature is V = 1321 m/s
