Chapter 10, Problem 128P

Saturated water vapor at $\text{40}°\text{C}$ is to be condensed as it flows through a tube at a rate of0.2 kg/s. The condensate leaves the tube as a saturated liquid at $\text{40}°\text{C}\text{.}$ and The rate of heat transferfrom the tube is

(a) 34 $\text{kJ/s}$

(b) 268 $\text{kJ/s}$

(c) 453 $\text{kJ/s}$

(d) 481 $\text{kJ/s}$

(e) 515 $\text{kJ/s}$
