For example if you have distance in miles and speed in kmh you will need to convert speed to mph or distance to kilometers. Calculations are based on the speed of sound at 21C 344. For fluids in general the speed of sound c is given by the NewtonLaplace equation.
C K s r displaystyle c sqrt frac K_ s rho where.
Where d is the distance travelled v is the speed velocity and t is the time so you can read it as Time Distance Speed. In our case 0 01 x 343 3 43 meters. By calculating the difference in time it takes sound to reach both ears c. The speed of sound in mathematical notation is conventionally represented by c from the Latin celeritas meaning velocity.
