The speed of sound in air at NTP is 332 ...

The speed of sound in air at NTP is 332 m/s. Calculate the percentage error in speed of sound as calculated from newton's formula. Given that the density of air is `1.293kg//m^(3)`.

Text Solution

Verified by Experts

From Newton's formula
At NTP, `P=1.01xx10^(5)Pa`
`v=sqrt((1.01xx10^(5))/(1.293))=280m//s`
Difference in velocity `=332-280=52m//s`
%error`=(52)/(332)xx100=15.7%`
