Steam Basics
What steam is, why industry runs on it, and how to read its numbers — the ground every other lesson stands on.
- A1Why steam runs industry100°7 minFour physical reasons a 300-year-old technology still carries most of the world's process heat — and where it genuinely doesn't fit.
- A2Pressure, temperature and the units India argues about100°8 minGauge vs absolute, kg/cm² vs bar vs psi — the unit confusions that break steam calculations, settled once, with a converter.
- A3What is steam?100°8 minEvaporation, boiling and the saturation curve — why every pressure has exactly one boiling temperature, and why that runs your plant.
- A4The steam phase diagram100°8 minWet, dry saturated and superheated steam on one picture — the bell curve and dryness fraction.
- A5How to read a steam table100°9 minhf, hfg, hg and vg — what each column means and how to pull the number you need.
- A6Latent heat — the workhorse100°7 minWhy the heat of condensation dwarfs everything else, and why condensate still carries a quarter of the energy.
- A7Superheated steam: friend and trap100°6 minWhere superheat helps, where it quietly ruins heat transfer.
- A8Flash steam explained100°8 minWhere flash steam comes from, how much forms, and why it is a resource, not a loss.
- A9Wet steam, air and clean steam100°7 minDryness, air blanketing and the hygiene grades — what steam quality really means.
- A10How much steam does a process need?100°7 minm·cp·ΔT, warm-up vs running load, and condensing rates — estimating demand honestly.
- A11Heat transfer with steam100°7 minU, A and ΔT — films, fouling, and what one percent of air does to a heat exchanger.
- A12The steam formulae crib sheet100°4 minEvery working formula on one printable page.
