The formula for speed of sound is. Density r 0043 kgm3. Speed can be calculated by dividing distance by time.
C_air 3313 x 1 T27315 ms You may think airs humidity would be a factor but this formula shows that is not the case.
V is the speed of sound and T is the temperature of the air. Take a number the next one in the sequence is the kilometres if the previous one was miles eg 50 mph is roughly 80 kph. K Bulk Modulus of Elasticity Pa psi r density kgm3 lbft3 This equation is valid for liquids solids and gases. The acoustic velocity can alternatively be expressed with Hooks Law as.
