Consider a model of finite control volume (volume V and surface area) fixed in space with elemental volume dV, vector elemental surface area d\(\vec{S}\), density ρ and flow velocity \(\vec{V}\). What is the mass inside the control volume?

• A. fixed in space with elemental volume dV, vector elemental surface area d\(\vec{S}\), density ρ and flow velocity \(\vec{V}\). What is the mass inside the control volume?a) \(\iint_s\rho \vec{V}.d\vec{S}\)
• B. \(\iiint_V\rho dV\)
• C. ρdV
• D. \(\frac{\partial}{\partial t} \iiint_V\rho dV\)
