Question: (a) Show that since the bulk modulus has SI units N/m 2 and mass density has SI units kg/m 3 , Eq. (12-1) gives the

(a) Show that since the bulk modulus has SI units N/m² and mass density has SI units kg/m³, Eq. (12-1) gives the speed of sound in m/s. Thus, the equation is dimensionally consistent.

(b) Show that no other combination of B and ρ can give dimensions of speed. Thus, Eq. (12-1) must be correct except for the possibility of a dimensionless constant.

a measure of the restoring force B (in fluids) (12-1) y =

a measure of the restoring force B (in fluids) (12-1) y = %3D a measure of the inertia
