A mixture of two diatomic gases exists in a closed cylinder. The volumes and velocities of sound in the two gases are V_1, V_2, c_1 and c_2respectively. Determine the velocity of sound in the gaseous mixture. (Pressure of gas remains constant),

Answer»

`c_1c_2 SQRT((V_1 + V_2)/(V_1c_2^2 + V_2c_1^2) )`
`c_2c_1sqrt((V_2^2 + V_1^2)/(V_1c_2^2 + V_2c_1^2))`
`c_2c_1 sqrt((V_2 - V_1)/(V_1c_2^2 - V_2c_1^2))`
`c_1c_2 sqrt((V_2 + V_1)/(V_1c_1^2 - V_2 c_2^2))`
