An industrial fan delivers 55,000 CFM of air through a discharge duct with a size of 3 ft x 4 ft where the static pressure is 6-inch water gage. At the inlet, the duct diameter is 4 ft and the static pressure is 1-inch water gage. The temperature of the air is 78 F and barometric pressure is 14 psia. (ρw = 62.2 lb/ft³). Determine: a). the total pressure in feet of air b). the static power in HP c). the fan power in HP
An industrial fan delivers 55,000 CFM of air
through a discharge duct with a size of 3 ft x 4
ft where the static pressure is 6-inch water
gage. At the inlet, the duct diameter is 4 ft and
the static pressure is 1-inch water gage. The
temperature of the air is 78 F and barometric
lb
pressure is 14 psia. Pw= (62.2 ft° ). Determine;
a). the total pressure in feet of air
b). the static power in HP
c). the fan power in HP
