Problem 5 (15 points). A rough method of scaling up cylindrical liquid-mixing tanks and impellers is to keep the power input per unit volume constant. If it is desired to increase the volume of a properly baffled liquid-mixing tank by a ratio of 3, by what ratio must the (5a) tank diameter and (5b) impeller angular velocity be changed? Assume mixing tanks are geometrically similar (that the height to diameter ratio remains constant), the liquid in both tanks is the same, and both operate in the complete turbulent region. The power supplied to the mixing propeller, P, may be assumed to be a function of the propeller diameter, D, its angular velocity ω, and liquid density p.

2. Consider the linear system t\dot{X} = AX, t > 0, where A is a constant matrix in $\mathbb{R}^{n \times n}$. (a) Find a scalar $\lambda$ and an $\mathbb{R}^n$ vector V, both constant, such that the vector-valued function $X(t) = e^{\lambda t}V$ is the solution of the given linear system. (b) Suppose that $A = \begin{pmatrix} 2 & -1 \ 3 & -2 \end{pmatrix}.$ Find the general solution of the corresponding system of differential equations. (c) Find the solution of the system in 2b if $X(0) = (1, 0)^T.$
