SI-Units

The sensible heat flow can be expressed in SI-units (metric) as

Q_s = c_p ρ q Δt / 3600         (1)

where

Q_s = sensible heat flow (kW)

c_p = specific heat of air (kJ/kg K)

ρ = air density at standard conditions (kg/m³)

q = air flow (m³/hr)

Δt = temperature (^oC)

English (Imperial) units

In English (imperial) units the sensible flow heat can be expressed as

Q_s= 60 c_p ρ q Δt = 1.075 q Δt         (2)

where

Q_s = sensible heat flow (Btu/hr)

c_p = 0.2388 - specific heat (Btu/lb^oF)

ρ = 0.075 - air density at standard conditions (lb/ft³)

q = air flow in (ft³/min)

Δt = temperature difference (^oF)
