After pressure spraying, there is a thin layer of water (at 70°F) left inside of a 24 inch diameter retort that is 20 ft. long. A jet heater is place in front of the entrance to the tube. The jet heater is turned on and produces 2000 ft³/minute of 120°F air. What is the mass transfer convection coefficient of the water into the air?

Question
Transcribed Image Text:**Problem Statement:**
After pressure spraying, there is a thin layer of water (at 70°F) left inside a retort with a diameter of 24 inches and a length of 20 feet. A jet heater is placed in front of the entrance to the tube. The jet heater is turned on and produces 2000 cubic feet per minute of air at 120°F. Calculate the mass transfer convection coefficient of the water into the air.
**Explanation of Terms:**
- **Retort:** A cylindrical container typically used in industrial processes.
- **Jet Heater:** A device used to heat air to a specific temperature and direct it into the retort.
- **Mass Transfer Convection Coefficient:** A measure of the rate of mass transfer from the water surface into the airflow, influenced by the air velocity and temperature difference.
This situation involves determining how effectively the heated air causes water to evaporate from the surface due to the convection process.
