Stream Bed Water-Side MTC

Use the von Karman analogy result Equation 2.19 to estimate the water-side coefficient for phenol in the Mississippi River. Velocity = 1.2 m/s and depth = 7.62 m. Phenol diffusivity in water is 0.84E - 5 cm /s and Sc = 1200 at 25°C. 

Solution It is assumed that a Manning s roughness coefficient n = 0.025 in Table 2.2 applies to the Mississippi River. Equation 2.25 is appropriate for estimating the friction factor, applying it yields  

Entering the appropriate numerical values into the denominator of Equation 2.19 yields a value of equal to 674. The computation is
