According to Riddle Spot, the answer to the riddle What goes up the chimney down but cannot go down the chimney up? is an umbrella. An umbrella is very thin and narrow when it is down, so it can fit through the narrow opening of a chimney. When an umbrella is up, however, it is too large to fit through the same narrow opening.
This pressure difference that pushes the hot gas up the flue gas stack or the chimney is the 'chimney or stack effect'. You can feel the effect if you stand near the doors or openings at the bottom of a stack or at open door of an elevator shaft.Depending on the height it can be gentle draught or heavy suction.or a thermal power plant with a stack height of 250 meters the effect could be around 77 mm of water column. In thermal power plants the stack effect aids the Induced draft fans in removing the hot flue gases from the furnace and dispersing them at the top of the stack.
