Steam at 0.080 bar is arranged to condense over a 50 cm square vertical plate. The surface temperature is maintained at 20oC.
Calculate the following.
a. Film thickness at a distance of 25 cm from the top of the plate.
b. Local heat transfer coefficient at a distance of 25 cm from the top of the plate.
c. Average heat transfer coefficient.
d. Total heat transfer
e. Total steam condensation rate.
f. What would be the heat transfer coefficient if the plate is inclined at 30oC with horizontal plane.
