Course details

This course teaches Heat and Mass Transfer (HMT) in a clear and easy way, covering the three main modes of heat transfer: conduction, convection, and radiation, along with heat exchangers. It explains important concepts like thermal conductivity, Fourier’s law, heat conduction in gases, fins, and transient conduction in conduction. In the convection part, you will learn about forced and natural convection, along with important dimensionless numbers like Reynolds, Prandtl, and Nusselt numbers, and heat transfer over flat surfaces and through pipes. The course also explains different types and classifications of heat exchangers, including concepts like LMTD, NTU, and fouling factor. In the radiation section, topics such as absorptivity, reflectivity, transmissivity, radiation laws, and shape factors are covered. The course includes formula derivations, numerical problems, examples, and advanced applications to help students understand the subject deeply. It is designed according to academic requirements of HMT for students. The first two lectures are free previews, where the syllabus and basic ideas of heat transfer modes are introduced. Students are recommended to watch these lectures before joining the course.

Questions and Answers

Q: You're reviewing a GA with an insulation callout and you google "how to read heat exchanger insulation thickness on GA drawing". The shell-side insulation is noted as "50 mm, k = 0.035 W/m·K @ 50°C". What heat transfer assumption is embedded in that note?

A: Governing principle: Insulation datasheets quote thermal conductivity for pure conduction. Applied here: The GA note gives k and thickness only, which supports a 1‑D conduction model through the layer; convection and radiation sit outside that boundary condition. Distractor trap: Option B sounds confident if you've mixed up overall U calculations with material properties, but k never bundles convection.

Q: Your lead asks you to sanity‑check a worked example and you search "steady state heat conduction through plane wall example W/m". A steel plate is 10 mm thick, k = 45 W/m·K, area = 1 m². One side is at 120°C, the other at 80°C. What is the steady heat transfer rate?

A: Governing principle: Fourier’s law for 1‑D steady conduction, q = kAΔT/L. Applied here: 45×1×40 / 0.01 gives 180,000 W, then check the decimal—10 mm is 0.01 m, not 0.1 m, landing at 18 kW. Distractor trap: Option A comes from slipping a zero on thickness, a mistake that survives many peer reviews.

Q: Process needs 5 kW of heat removal from air at 40°C using cooling water at 25°C. You search "air to water heat exchanger selection low duty". Space is tight and fouling is expected on the air side. Which configuration fits best?

A: Governing principle: Low gas-side h dominates thermal resistance in gas–liquid exchangers. Applied here: Fins on the air side raise effective area without killing maintainability, which matters once fouling shows up. Distractor trap: Plate exchangers look compact, but air-side pressure drop and fouling make them a field headache.

Q: During a HAZID you google "loss of cooling heat exchanger consequence analysis". Cooling water to a jacketed vessel fails while heat input continues. Which physical outcome happens first?

A: Governing principle: Energy imbalance shows up as temperature rise before mechanical failure. Applied here: With heat input ongoing, contents heat up, vapor pressure climbs, and pressure follows; shock and water hammer aren’t the first-order response. Distractor trap: Option B sounds dramatic but ignores the time constant of the metal wall.
