Question

(3) Water is used as the working fluid in a Carnot cycle. Boiling takes place at 295°C

and heat is rejected at 150°C. During heat addition, the fluid changes from a saturated

liquid to a saturated vapor. (a) Sketch this Carnot cycle on a TS diagram and label

the heat addition/rejection and work expansion/compression. (b) What is the quality

at the end of expansion? (c) What is the quality at the beginning of compression? (d)

Compute the expansion work in kJ/kg?
