1.	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 ?
Answer» Solution :Bulkmodulus ` B=v \|(Delta p)/( Delta v)\| = ( 100 xx10^3 )/( 0.005 xx 10^(-2))` ` B= 2000Mpa` (b) ` V=sqrt((B)/( RHO)) = sqrt(( 2000xx 10^(6) )/( 1000))` ` V = 1414 ms^(-1)`
