Saturated steam at 60 ºC is condensed over an array of 100 horizontal tubes, each with a diameter of 1.2 cm and a length of 3 m. The tube surfaces are maintained at a uniform temperature of 30 ºC. a) What is the pressure of the steam? _____________ kPa. (Note that this could have been given instead of steam T.) Determine the condensation rates on the tubes for b) a rectangular array of 5 tubes high by 20 tubes wide and c) a square array of 10 tubes high by 10 tubes wide. Compare and discuss the results of b) and c). d) Brief physical explanation of how the results compare:

An air-cooled steam condenser is operated with air in cross flow over a square, in-line array of 400 tubes (NL=NT= 20), with an outside tube diameter of 20 mm and longitudinal and transverse pitches of SL= 60 mm and ST= 42 mm, respectively. Saturated steam at a pressure of 2.455 bars enters the tubes, and a uniform tube outer surface temperature of Ts= 390 K may be assumed to be maintained as condensation occurs within the tubes.

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.
