Note: The Pitot tube constant is determined on the basis of the following units:
m/s[g/g mole (mm Hg)/(K)(mm H
= velocity pressure, mm H2O
= temperature, K
= barometric pressure, mm Hg
= duct static pressure, mm Hg
m = 3600VAp
= mass flow rate, kg/h
= air flow velocity, m/s
= number of seconds per hour
= duct cross-sectional area, m2
= density of air at standard temperature and pressure (use 1.204 kg/m3)
Δe = Δh × m
= rate of heat release into the circulating air, kJ/h
= change in enthalpy of the circulating air, kJ/kg
= mass air flow rate, kg/h
E = ∑(Δe × i) for i= t to t
t 1 2
= delivered heat output over any time interval t
= time interval for each measurement, h
e = E /t
t t
= average heat output, kJ/h
