Steam side heat transfer co-efficient in an evaporator is in the range of ______________ kcal/hr.m2°C?
Correct answer: D. 5000-15000
- A. 10-50
- B. 100-500
- C. 1000-1500
- D. 5000-15000
Explanation
Condensing steam provides a high heat-transfer coefficient, typically about 5000–15000 kcal/(h·m²·°C) in evaporators. The lower ranges are more characteristic of less effective heating or single-phase fluids.
