Q$2.$ From Reynold transport theorem, write conservation of mass equation for a fixed control volume, uniform, steady state, and incompressible flow? Water at $0\mathrm{.}1\frac{m^3}{h}$ and alcohol $)=(0\mathrm{.}8$ at $0\mathrm{.}3\frac{m^3}{s}$ are mixed as shown in Figure $1.$ What is the average density of the mixture of alcohol and water? Know: density of water is $1000k\frac{g}{m^3}.$
