A steady‐flow gas furnace supplies hot air at a rate of 850 cfm and conditions of 120F and 1.00 atm. The air splits into two branches: a 10" diameter duct and a 12" diameter duct. The velocity in the 12" diameter duct is 800 ft/min.
Determine:
(a) The volumetric flow in the 12"‐dia. duct.
(b) The velocity in the 10"‐dia. duct.
(c) The volumetric flow rate into the furnace if the air enters at 68F and 1.00 atm.
(d) The mass flow rate of air entering the furnace.
