a. 1 PSI = 2.31 ft of waterb. power factor = True Power (Mw)/ Apparent Power (MVA)
c. 7.48 gallons of water = 1 ft3 of waterd. 1 foot of water head = 2.31 psi
e. psig = psia 14.7
psia = psig + 14.7f. conversion of gas concentrations to 7% oxygen
CO @ 7% O2 = CO X (21 - 7)/(21- O2)(SEE PAGE 15-7 OF MWC MANUAL)
g. conversion of particulates to 7% Oxygen
PM @ 7% O2 = PM X (21 - 7)/(21- O2)
(SEE PAGE 15-7 OF MWC MANUAL)
h. COMBUSTION EFFICIENCY
CE = 100% X CO2 / (CO2 + CO)
i. 1 BTU = 1,055 Joules
1 hp-hr = 746 watts
