Compute the Reynolds number for the flow of ethylene glycol at \( 25^{\circ} \mathrm{C} \) through the section shown in Figure Q3(b). The volume flow rate is \( 0.16\left(\mathrm{~m}^{3} / \mathrm{s}\right) \). If the inside dimension of each side of the square is \( 250 \mathrm{~mm} \) and the outside diameter of the tube is \( 150 \mathrm{~mm} \). [20 Marks] Figure Q3(b)
