How do you convert inches of water column into cubic feet per minute?
You can convert in w.c. to feet per minute and then convert fpm to CFM. FPm is 4005 times the square root of the pressure. So to convert 1 " w.c. to fpm its the square root of 1, which is 1 times 4005, which is 4005 fpm. Then you multiply the fpm by the area of the space the air is moving through. So if you have 1 " wc moving through a hole that's 1 square foot in area, that's 4005 cubic feet per minute.

If a sky driver is falling at about 176 ft per second how many feet per minute is he falling?
10560 fpm
How do you convert 2288 feet per minute to miles per hour?
2288 fpm times 60 = 137,280 fph 137,280 divided by 5280 = 26 mph
How to calculate required fiter area from blowers CFM?
This will depend greatly on the filter you want to use. A flat filter will need to be larger than a pleated filter. Determine what efficiency you need from your air filter. Look up the maximum "face velocity" across the filter, most are around 500fpm. Divide the blower cfm by the filter fpm and you will end up with ft2 or filter needed. Let's do an example of a 2000cfm blower with a filter that requires a face velocity of 400feet/min. 2000ft3/m / 400ft/m = 5ft2 or (1)24"x30" filter.
