solvent, then it is called a ‘hydrate’
B. In heat exchanger calculations (Δt) weighted is used in place of Δt, when it involves more
than one sequence of heating or cooling i.e., desuperheating & condensation or condensation
& sub-cooling
C. Heat transfer co-efficient during nucleate boiling is not influenced by the agitation imparted
D. In case of short tube vertical evaporators, area of central downtake is about 50 to 100% of the
total tube cross-sectional area
Correct Answer: Heat transfer co-efficient during nucleate boiling is not influenced by the agitation imparted ✔
