TEST REPORT FOR HY-C COMPANY, LLC Report No.: 104415176MID-002AR2 Date: 11/09/21

m/s[g/g mole (mm Hg)/(K)(mm H 2 O)] 0.5

Δ P

= velocity pressure, mm H2O

T = temperature, K 28.56 = molecular weight of air P Baro

= barometric pressure, mm Hg = duct static pressure, mm Hg

P s

The mass flow rate shall be calculated as follows:

m = 3600VAp

where: m

= mass flow rate, kg/h

V = air flow velocity, m/s 3600 = number of seconds per hour A = duct cross-sectional area, m2 p

= density of air at standard temperature and pressure (use 1.204 kg/m3) The rate of heat release into the circulating air shall be calculated using the air flow and change in enthalpy, as follows:

Δ e = Δ h × m

Where: Δ e

= rate of heat release into the circulating air, kJ/h = change in enthalpy of the circulating air, kJ/kg

Δ h

m

= mass air flow rate, kg/h

The heat output over any time interval shall be calculated as the sum of the heat released over each measurement time interval, as follows:

E t = ∑ ( Δ e × i) for i= t 1 to t 2

Where: Et

= delivered heat output over any time interval t 2 –t 1 , kJ

i

= time interval for each measurement, h

The average heat output rate over any time interval shall be calculated as follows:

e t = E t /t

where e t

= average heat output, kJ/h

t

= time interval over which the average output is desired, h
