The Speed of Sound in a Fluid Can Be Calculated $$v = \sqrt { \frac { B } { \rho } }$$

Essay

The speed of sound in a fluid can be calculated using the following equation: $$v = \sqrt { \frac { B } { \rho } }$$
where
$$\begin{array} { l } v = \text { speed of sound in } \mathrm { m } / \mathrm { s } \\B = \text { bulk modulus } \\\rho = \text { fluid density in } \mathrm { kg } / \mathrm { m } ^ { 3 }\end{array}$$
What is the appropriate unit for $B$ if the preceding equation is to be homogeneous in units?
