4.3.4 Example A: Wetted bulb analogy

Course subject(s) 4. Mass transfer

We can combine heat and mass transfer together to calculate the wetted bulb temperature. We can also apply this for dissolving spherical calcium chloride crystals in a liquid, because you get a small dissolving fluid around the sphere with a concentration . The crystal sphere has a temperature . Water with a temperature and a concentration of crystal is flowing around the crystals. Find with the mass flow and heat flow, the temperature difference between the water and the crystal.

Lewis number is in this case 140. Furthermore, the molecular weight of calcium chloride , and .
