Blowdown Percentage

Feedwater flow is 52 t/h and steam generation is 50 t/h. Neglect other losses. Calculate blowdown as percentage of feedwater.

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.
