Question
1. 400,000 Ibm/hr of 270°F water is to be heated to 370°F by condensing saturated
390°F steam. (The steam does not sub cool upon condensing). Your job is to design
the heat exchanger. The following parameters represent constraint your design.
number of tube passes
4
tube fluid
water being heated
number of shell pass
shell fluid
steam being cooled
U (based on outside tube area)
700 BTU/hr – ft² – °F
1 in
tube outside diameter
tube wall thickness
1/16 in
bulk tube fluid velocity
5 ft/s
(a) How many tubes are required per pass?
(b) How many tubes are required total?
(c) Allowing 3 ft for headers and flanges, how long should the exchanger be?
