Corrosion and Erosion takes place if dryness factor of steam is __________ in last stage.
A. less than 0.68
B. more than 0.60
C. less than 0.88
D. none of the mentioned
Answer:A
Corrosion and Erosion takes place if dryness factor of steam is __________ in last stage.
A. less than 0.68 B. more than 0.60 C. less than 0.88 D. none of the mentioned
Explanation: Liquid particles have lesser velocity than steam particles and hence if dryness fraction is less than 0.88 even erosion and corrosion can takes place.
