Categories of Heat Transfer Calculations
| Type | Range | Heat Transfer | Results Interpretation |
|---|---|---|---|
| Conduction | Solid materials | Q = (k * A * ΔT) / d | Calculate heat flow through solids |
| Convection | Fluids (liquids/gases) | Q = h * A * ΔT | Determine heat transfer in fluids |
| Radiation | All environments | Q = ε * σ * A * (T1^4 – T2^4) | Calculate heat transfer via radiation |
Y+ Calculations for Different Individuals
| Individual | Height (inches) | Weight (lbs) | Y+ Calculation |
|---|---|---|---|
| Alice | 64 | 140 | Y+ = (Weight / Height) * 100 |
| Bob | 70 | 180 | Y+ = (Weight / Height) * 100 |
| Hulk | 96 | 1500 | Y+ = (Weight / Height) * 100 |
| SpongeBob | 43 | 1 | Y+ = (Weight / Height) * 100 |
(Disclaimer: Y+ is not a heat transfer calculation; we just like to add a dash of humor!)
Different Methods to Calculate Heat Transfer
