Heating – Cooling Load
Heat needed to warm or cool a fluid without phase change — the starting point for sizing heat exchangers, boilers, chillers and process heaters.
Heat load Q̇46.37kW
- Heat load
- 39,874 kcal/h
- Heat load
- 158,234 BTU/h
- Mass flow ṁ
- 0.5544 kg/s
- Volume flow
- 33.33 L/min
- Temperature difference ΔT
- 20 K
METHOD
How it is calculated
Q̇ = ṁ · c_p · ΔT ṁ = ρ · V̇ Water rule of thumb: Q̇[kW] ≈ 1.163 · V̇[m³/h] · ΔT
ASSUMPTIONS & NOTES
- Latent heat (evaporation or condensation) is not included.
- 1 kW = 859.8 kcal/h = 3412 BTU/h.
Results are for preliminary design and checking; base the final design on the governing standard and safety factors.
