Question

speed of sound through a gas is measured at 340 meter
per second at pressure P1 and temperature T1 what will be the speed of sound if pressure of gas is doubled the temperature is kept constant ​

Answer 1

Explanation:

Speed of sound c ≈ 331.3 + (0.6 × ϑ) in m/s.

That gives e.g. at a temperature of ϑ = 20°C a speed of sound of: c ≈ 331.3 + (0.6 × ϑ) = 331.3 + (0.6 × 20) = 343.3 m/s.
