Find speed of sound in hydrogen gas at 2...

Find speed of sound in hydrogen gas at `27^(@)` . Ratio `C_(p)//C_(V)` for `H_(2)` is `1.4` . Gas constant `R =8.31 J//mol -K` .

Text Solution

Verified by Experts

The correct Answer is:
A, B, C
`:. nu =sqrt((gammaRT)/(M)`
Here, `T = 27 +273 = 300K` , `gamma = 1.4` , `R = 8.31 J//mol - K` , `M =2xx 10 ^(-3) kg// mol`
`:. nu =sqrt((1.4xx8.31xx 300)/(2xx 10^(-3))`
`= 1321 m//s`
