An organic liquid (1-propanol at 1 bar) is to be vaporized inside a set of vertical 1-in
Question:
An organic liquid (1-propanol at 1 bar) is to be vaporized inside a set of vertical 1-in BWG 16 tubes using condensing steam on the outside of the tubes to provide the energy for vaporization. The major resistance to heat transfer is expected to be on the inside of the tubes, and the wall temperature, as a first approximation, may be assumed to be at the temperature of the condensing steam, which for this case is 110°C. It may be assumed that the value of the vapor quality, x, varies from 0.01 to 0.99 in the tube. The flow and other physical parameters for the organic liquid are
Determine the average heat transfer coefficient and the length of the tube needed to vaporize the liquid in this vertical reboiler.
