Heat transfer help is one-to-one support from an engineering tutor who explains how heat moves by conduction, convection and radiation, and helps you solve problems and write lab reports. For heat exchanger sizing with LMTD, see chemical engineering help.

A wall has 0.2 m of brick (k = 0.7 W/m·K) and 0.05 m of insulation (k = 0.04 W/m·K). Inside h = 10 W/m²·K, outside h = 25 W/m²·K and the temperature difference is 30 K. Work per square metre.
| Resistance | Working | Value (m²·K/W) |
|---|---|---|
| Inside convection | 1 ÷ 10 | 0.100 |
| Brick | 0.2 ÷ 0.7 | 0.286 |
| Insulation | 0.05 ÷ 0.04 | 1.250 |
| Outside convection | 1 ÷ 25 | 0.040 |
| Total | Sum | ≈ 1.676 |
U = 1 ÷ 1.676 ≈ 0.60 W/m²·K, so the heat flux is 0.60 × 30 ≈ 17.9 W/m². The insulation provides about three-quarters of the total resistance.
Two standard problems.
| Question | Working | Answer |
|---|---|---|
| A 1 m² surface (ε = 0.8) at 500 K radiates to surroundings at 300 K. Net heat loss? | 0.8 × 5.67 × 10⁻⁸ × (500⁴ − 300⁴) | ≈ 2,470 W |
| Critical insulation radius for a pipe with k = 0.04 W/m·K and h = 10 W/m²·K | r_c = k ÷ h | 0.004 m (4 mm) |
| Convection from 2 m² at h = 25 W/m²·K and ΔT = 40 K | Q = hAΔT | 2,000 W |
Adding insulation to a pipe smaller than the critical radius can increase heat loss at first, because the outer surface area grows.
Tutors match your level, syllabus and exam board, from school to PhD.

Most lost marks come from unit errors and using the wrong correlation.
| Mark-loser | What to do instead |
|---|---|
| Celsius in radiation equations | Use kelvin in the Stefan–Boltzmann law |
| Resistances added in parallel incorrectly | Draw the thermal circuit first |
| Wrong convection correlation | Check the flow type, geometry and Reynolds number range |
| Lumped capacitance used when Bi > 0.1 | Check the Biot number first |
| Fluid properties at the wrong temperature | Evaluate properties at the film or mean temperature |
| No units | Give units at every step |
Heat transfer is assessed in several formats, and each one is marked on different things. Tutors help you understand the brief and the marking criteria before you start.
| Assessment | What markers look for |
|---|---|
| Problem sets | Accurate solutions with assumptions stated |
| Exams | Conduction, convection and radiation problems |
| Lab reports | Experimental heat transfer coefficients compared with theory |
| Design tasks | Insulation or heat exchanger design |
| Simulation projects | CFD or numerical conduction models |
Heat transfer students use these tools.
| Tool | What it is used for |
|---|---|
| Property tables | Thermophysical properties |
| Excel or MATLAB | Calculations and numerical methods |
| ANSYS Fluent or COMSOL | Thermal simulation |
| Heisler charts | Transient conduction |
| Thermocouples and data loggers | Lab measurements |
Heat transfer is taught to similar core ideas worldwide, but grading, referencing and course structure differ. FLN tutors work from your own syllabus and handbook and schedule lessons in your time zone. Always follow your module handbook for referencing.
| Country | Where heat transfer is studied | Grading | Referencing usually used |
|---|---|---|---|
| United Kingdom | BEng mechanical and chemical engineering | GCSE 9–1, A-level A*–E; degrees First, 2:1, 2:2, Third | IEEE or Harvard |
| United States | Heat transfer courses in engineering programmes | Letter grades A–F and a 4.0 GPA scale | IEEE |
| Australia | Mechanical and chemical engineering degrees | HD, D, C, P at university; ATAR for school leavers | IEEE or Harvard |
| Canada | Engineering programmes | Letter grades or percentages; GPA scales vary by province and university | IEEE |
| India | B.Tech/BE mechanical and chemical engineering heat transfer and GATE | Board exam percentages; university CGPA, often on a 10-point scale | IEEE |
Students in Ireland, the Gulf, Europe, Africa and Asia can book the same help, with lessons in their own time zone.
The price of heat transfer help depends on the type of task and your deadline. A short problem costs less than a full design task. You always see the price first: a fixed quote for homework and assignment guidance, or the tutor's hourly rate for live lessons, with no contract and no minimum number of sessions. Refunds follow our refund policy.

Yes. Tutors explain concepts and work through problems and lab reports, within your university's rules.
Conduction, convection and radiation.
Heat flux by conduction is proportional to the temperature gradient: q = −k dT/dx.
A measure of opposition to heat flow, such as L ÷ kA for conduction or 1 ÷ hA for convection.
The overall heat transfer coefficient, the inverse of the total thermal resistance per unit area.
The radius at which heat loss from an insulated cylinder is greatest: r_c = k ÷ h.
Bi = hL ÷ k, comparing internal conduction resistance with surface convection resistance.
When the Biot number is below about 0.1, so the temperature inside the body is nearly uniform.
Nu = hL ÷ k, the ratio of convective to conductive heat transfer.
Forced convection uses a fan or pump; natural convection is driven by buoyancy.
Emitted radiation is q = εσT⁴, with σ = 5.67 × 10⁻⁸ W/m²·K⁴.
The fraction of radiation leaving one surface that reaches another.
The ratio of actual fin heat transfer to that if the whole fin were at base temperature.
A heat exchanger method using effectiveness and the number of transfer units, useful when outlet temperatures are unknown.
It has many correlations; drawing thermal circuits makes problems easier.
Tutors work from your course text, such as Incropera, Cengel or R.K. Rajput.
Often, yes, for short problems, depending on tutor availability.
Yes. Tutors use GATE-style problems for practice.
Yes. Tutoring, worked examples and feedback are a normal part of learning. You should use the explanations to understand the method and submit your own work in line with your school's or university's academic integrity rules. See our academic integrity policy.
Yes. Your files and details are used only to help you and are not shared with your school or university. See our privacy policy.
