Sensible Heat Energy Calculator: worked example
This example is generated from PROFENG's own default input set and the implemented relationship. It is not copied from a cited publication.
Relationship
Q = m cp ΔT
This calculator determines heat energy from mass, specific heat, temperature change. Use it to screen energy, temperature and heat-transfer relationships with explicitly stated properties and boundary conditions.
Inputs
- Mass (mass) = 100 kg
- Specific heat (cp) = 4.186 kJ/(kg·K)
- Temperature change (deltaT) = 20 K
Working
(100)*(4.186)*(20) = 8,372 kJ
Heat energy: 8,372 kJ
Assumptions and limits
- Properties entered by the user are treated as constant over the calculation unless the formula explicitly varies them.
- Temperatures and temperature differences must use the unit convention shown by the calculator.
- The model is lumped or one-dimensional where implied by the displayed relationship.
- No phase change is represented.
- The entered specific heat is treated as constant over the temperature interval.
- Mass, specific heat and temperature difference use the calculator's compatible unit basis.
- Heat losses, work interactions and other energy terms are excluded unless represented separately.
