If C=332 m s^(-1), say the velocity of sound in dry air at STP, find the velocity of sound in loist air at STP. Molecular weight of air =28.8, that of water vapour =18, gamma of dry air =1.4 and gamma of water vapour =1.33. The standard pressure is 750 mm of mercury and standard temperature is 0^(@)C. the vapour pressure at 0^(@)C is 4.8 mm of mercury.

1.	If C=332 m s^(-1), say the velocity of sound in dry air at STP, find the velocity of sound in loist air at STP. Molecular weight of air =28.8, that of water vapour =18, gamma of dry air =1.4 and gamma of water vapour =1.33. The standard pressure is 750 mm of mercury and standard temperature is 0^(@)C. the vapour pressure at 0^(@)C is 4.8 mm of mercury.
Answer» ANSWER :`331.7 m s^(-1)`
