C. Most concentrated liquid is at highest temperature
D. Equal heat transfer co-efficients exist in various effects
A. White & rough

A. (COP)R = (COP)HP = 0.6
B. (COP)R = 2.5; (COP)HP = 1.5
C. (COP)R = 1.5; (COP)HP = 2.5
D. (COP)R = (COP)HP = 2.5
A. Presence of a non-condensable gas decreases the condensing film co-efficient
B. Gases under high pressure are routed through the tube side, because high pressure gases are
corrosive in nature
C. Gases to be heated/cooled is normally routed through the shell side, because the corrosion
caused by the cooling water or steam condensate remain localised to the tubes
D. All A, B. & C.
