Given the following parameters for a fluid flow, calculate the appropriate quantities: \[ V_0 = 1 \, \text{m/s}, \quad P_r = 7.01, \quad \nu = 10^{-6} \, \text{m}^2/\text{s} \] \[ S_{hn} = \frac{4.91}{\sqrt{Re_x}}, \quad \Delta x = 0.01 \, \text{m} \]

Mean Residence Time Calculation for a given system: \[ t_m = \int_0^{\infty} t E(t) \, dt \] Where \( E(t) \) is the distribution function. For the given system, the distribution function is: \[ E(t) = 1 - 2t, \quad t \leq 0.5 \] \[ E(t) = 0, \quad t > 0.5 \]
