H.W (2) 7000 lb/hr of cracked gas of 20560 Btu/lb NHV is used as a fuel in a furnace. The radiant section absorbed 44500 Btu/hr ft2 of projected area. The tubes are 5 in. OD. ,10 in. spacing, and 20 ft long. They arranged in two rows. The air to fuel ratio is 21.0. Calculate 1) the number of tubes in the radiation section 2) the amount of heat absorbed in this section.
