Calculate the velocity of sound on a day when relative humidity is `80%` and tamperature and pressure are respectively `25^(@)C` and `0.68 m` of mercury. (velocity of sound at `STP=332 m s^(-1)`. Saturated vapour pressure at `25^(@)` is `0.026 m` of mercury.)

Calculate the velocity of sound in air on a day when temperature is 30^(@)C , pressure 0.74 m of mercury and relative humidity 60% . Velocity of sound at NTP =330 m s^(-1) . Saturated vapour pressure at 30^(@)C=0.032 m of mercury. [["Hint: Relative Humidity "=("Vapour pressure at "30^(@)C)/("Saturated vapour pressure at "30^(@)C)],[C_(m)=C_(d) sqrt(P/(P-0.385f))]]

The velocity of sound in vacuum is __ m s^(-1)

Calculate the velocity of sound in air saturated with moisture at 25^(@)C and 745 mm pressure. The saturation pressure at 25^(@)C is 23.76 mm of mercury and the velocity of sound at 0^(@)C in dry is 332 m s^(-1) . [Hint: See example 4.]

Calculate the velocity of sound in moist air at 27^(@)C and 0.7 m pressure. The dew point is 15^(@)C . The saturated vapour pressure at 15^(@)C is 17 mm of mercury and velocity of sound at 0^(@)C in dry air is 330 m s^(-1) .

If the velocity of sound in air is 332 meters per second at NTP, find the velocity at 30^(@)C and 0.7 m of mercury.

The velocity of sound in air at NTP is 330 m/s. What will be its value when temperature is doubled and pressure is halved ?

The velocity of sound in air at NTP is 330 m/s, What will be its value when temperature is tripled and pressure is halved ?

If the velocity of sound in air at 0^(@)C " is " 332 ms^(-1) , its velocity at 30^(@)C is
