The specific heat capacity of air is very nearly 1 kilojoule per kilogram per degree celsius, so assume that value. 1 BTU is 1.055 kilojoules, so 6349 BTU is 6698 kilojoules. now we have to decide what temperature rise to allow, you don't mention that. Shall we say 5 deg celsius? Then the heat balance is: 6698 = m x 5 , m = 6698/5 = 1340 kg air per hour. Density of air is about 1.25 kg per cubic meter, so 1340 kg = 1072 m3 = 38,216 ft3/hour or 10.6 cubic feet per second (1 cubic meter = 35.3 cubic feet). Remember this is for a 5 deg rise in air temperature. I'm not sure what power you will need to blow that much air, but there will be some rise in air temperature over the fan, before it gets to the cabinet. I can only give you the air flow required, the actual desired temperature of the cabinet is important too and you might need to cool the air flow before it reaches the cabinet.
Remember K H D | d c m (kilo, hecto, deka, (liter, meter, gram), deci, centi, milli). These are the denominations you need to list when converting metric units. Kilograms are three places to the left of grams. So you have to move the decimal place three times to the left (same as dividing by 1000). You will get 1.06 g = .00106 kg.
There are 100 square millimetres in one square centimetre. Therefore, 13.4 square centimetres is equal to 13.4 x 100 = 1340 square millimetres.
35% of 1340 = 35% * 1340 = 0.35 * 1340 = 469
1340 kilograms, in kg is 1340.
It is: 1340/2 = 670

1340 centimeters = 13.4 meters
The positive integer factors of 1340 are: 1, 2, 4, 5, 10, 20, 67, 134, 268, 335, 670, 1340
1%% rate:= 13.4/1340 * 100%= 0.01 * 100%= 1%
