Chapter 9, Problem 81CP

The general cool volume from of linearmomentum equation is
${\displaystyle \underset{CV}{\int }\rho \stackrel{\to }{g}dV+}{\displaystyle \underset{cs}{\int }{\sigma }_{ij}\cdot \stackrel{\to }{n}dA={\displaystyle \underset{cv}{\int }\frac{\partial }{\partial t}\left(\rho \stackrel{\to }{V}\right)}dV+{\displaystyle \underset{CS}{\int }\left(\rho \stackrel{\to }{V}\right)}\stackrel{\to }{V}\cdot \stackrel{\to }{n}dA}$
Discuss the meaning of each term in this equation. The terms are labeled for convenience. Write the equation as a word equation.
