Saturated, pure steam at a temperature of Tv = 170 oC (pressure P = 0.8 MPa) condenses
Fantastic news! We've Found the answer you've been seeking!
Question:
Saturated, pure steam at a temperature of Tv = 170 oC (pressure P = 0.8 MPa) condenses on
the outer surface of a vertical tube of outer diameter D = 2 cm and length L = 1.5 m. The tube
is maintained at a uniform temperature Tw = 150 oC.
All properties can be found from external sources, and should be evaluated at the temperature
of the steam.
Calculate:
(a) the local film condensation heat-transfer coefficient at the bottom of the tube.
(b) the average condensation heat-transfer coefficient over the entire length of the tube.
(c) the total condensation rate at the tube surface.
