Problem
Feedwater flow is 52 t/h and steam generation is 50 t/h. Neglect other losses. Calculate blowdown as percentage of feedwater.
Given Data
Write all quantities in consistent SI units before substitution.
Formula and Solution
Blowdown = 52 − 50 = 2 t/h. Percentage of feedwater = 2/52 × 100 = 3.85%.
Engineering Check
Check units, magnitude and physical meaning. State any simplifying assumptions and avoid mixing mass flow per hour with energy per second.
Practice Variation
Repeat the problem after changing one input by 10% and explain how the answer responds.
