Dimensional analysis has shown the following parameters to be significant for forced convection:
$\frac{x v_{\infty} ρ}{μ} \frac{μ c_{ρ}}{k} \frac{h x}{k} \frac{h}{ρ c_{p} v_{\infty}}$
Evaluate each of these parameters at 340 K, for air, water, benzene, mercury, and glycerin. The distance x may be taken as 0.3 $m, v_{\infty} = 15 m, x^{2} s$ , and h=34 $W x^{2} m^{2} \cdot K$ .
