By example, your bathroom is 8'W x 10.5L which is 84sq.ft You would then multiply that by the ceiling height to get cubic feet in the room. For the purpose of this example I will assume an 8' ceiling, thus we get 84sq.ft x 8' height equals 672cubic feet. The total volume of the room in 672cu.ft and we want 4 air exchanges per hour so we would need to move 672cu.ft x 4 = 2688cu.ft per hour.
The Gobi is a large desert region in Asia covering parts of northern and northwestern China, and of southern Mongolia. The Gobi measures over 1,610 km (1,000 mi) from southwest to northeast and 800 km (497 mi) from north to south.
The Gobi Desert is a large desert area in Northern China and Southern Mongolia. The word Gobi means 'very large and dry' in Mongolian, hence the name. Unlike the sandy Sahara, the Gobi Desert is comprised mainly of barren expanses of gravel plains and rocky outcrops. Summer sees the temperature rise up to 40Â°C (104Â°F), but it can also drop to -40Â°C (-40Â°F) in winter. Legend tells that the Gobi Desert was created when a Mongolian chief, skilled in the art of black magic, was forced to leave town with the Chinese army in hot pursuit.
