1. Determine the total condensation rate and heat transfer rate for the process of Problem 10.46 when the pipe is oriented at angles of θ = 0, 30, 45, and 60° from the horizontal.
2. A horizontal tube of 50-mm outer diameter, with a surface temperature of 34°C, is exposed to steam at 0.2 bar. Estimate the condensation rate and heat transfer rate per unit length of the tube.
