Question

find the speed of sound in air at 50°C and 70°C (take speed o sound 332 m/s)​

Answer 1

V(t) = v(0) + 0.61t

In this case v(0) is equal to 332 m/s. Temperature change is 50°C. Therefore speed of sound at 50°C is

332+(0.61×50)= 332+30.5= 362.5m/s

V(t) = v(0) + 0.61t

In this case v(0) is equal to 332 m/s. Temperature change is 70°C. Therefore speed of sound at 70°C is

332+(0.61×70)= 332+42.7= 374.7m/s
