Solve the following examples.

The speed of sound in air at 00C is 332 m/s. If it increases at the rate of 0.6 m/s per degree, what will be the temperature when the velocity has increased to 344 m/s?

Given:

Speed of sound in air at 00C = 332m/s


Speed increases at a rate of 0.6m/s per degree


Temperature at 344 m/s = T0c


Difference in velocities = 344 m/s - 332 m/s


= 12 m/s


Increase in temperature corresponding to the increase in velocity =


12/0.6 = 200C


Therefore temperature at velocity 344m/s = 00C + 200C = 200C
