An increase in pressure of 100 kPa causes a certain volume of water to decrease by 0.005% of its original volume .
(a) Calculate the bulk modulus of water ?
(b) Compute the speed of sound (compressional waves) in water ?

Text Solution

Verified by Experts

Bulk modulus
` B=v |(Delta p)/( Delta v)| = ( 100 xx10^3 )/( 0.005 xx 10^(-2))`
` B= 2000 Mpa`
(b) ` V= sqrt((B)/( rho)) = sqrt(( 2000xx 10^(6) )/( 1000))`
` V = 1414 ms^(-1)`
