There is a condenser that is made up of a horizontal tube bank (0.25 m long, 125 mm diameter). Saturated steam at 143.3 kPa is being condensed on the outside surface of the tubes, and the surface temperature is maintained at 90°C. Find the condensation rate and heat transfer coefficient if the bank consists of 15 tubes.

Soru 5) An uninsulated steam pipe with an outside diameter of 57 mm passes through a room in the basement. If the pressure of the saturated steam is 200 kPa and the room temperature is 15 oC, compare the results by calculating the amount of heat transfer from 1 m of the pipe to the room separately using natural convection and condensation heat transfer routes. Take the pipe surface temperature 120 oC.
