Evaporation of 1kg of water from a solution in a single effect evaporator requires about ________________ kg of steam?
Correct answer: B. 1-1.3
- A. 0.4 - 0.6
- B. 1-1.3
- C. 1.8-2
- D. 2 - 2.4
Explanation
In a single-effect evaporator, roughly 1 kg of steam supplies the latent heat needed to evaporate 1 kg of water, with the practical requirement often near 1 to 1.3 kg. Multiple effects improve steam economy by reusing vapour, unlike a single effect.
