Air temperature in the Rajasthan deserrt...

Air temperature in the Rajasthan deserrt can reach `46^(@)C`. What is the velocity of sound in air at that temperature ? `(V_(0)=331ms^(-1))`.

Text Solution

Verified by Experts

Velocity of sound in gas at `0^@ C `
`v_0 = 331 ms^(-1)`
Air temperature in Rajasthan,
`T = 46^@C`
`v_T=(v_0+0.61T)`
`= 331 + (0.61 xx 46)`
= 331 + 28.06
`v_T = 359.06 ms^(-1)`.
