Evaporation rate of water from the plate

Assignment Help Mechanical Engineering
Reference no: EM13946775

Dry air at 35°C and a velocity of 20 m/s flows over a wetted plate of length 500 mm and width 150 mm. An embedded electrical heater supplies power to maintain the plate surface temperature at 20°C.

(a) What is the evaporation rate (kg/h) of water from the plate? What electrical power is required to maintain steady-state conditions?

(b) After a long period of operation, all the water is evaporated from the plate and its surface is dry. For the same free stream conditions and heater power of part (a), estimate the temperature of the plate.
