2% of 30000 = 2% * 30000 = 0.02 * 30000 = 600
7 % of 30000 = 7/100 * 30000 = 0.07 * 30000 = 2100
30000
30000 or 30000 over 1 _____ 1
36% of 30,000= 36% * 30000= 0.36 * 30000= 10,800

times 60
1 cfh = 1 mbh
Equal in what way?

0.00108 square miles.
scfh is a measure of fan capacity. standard cubic feet per hour measured at 60 degrees fahrenheit and 14.696 psia. (22C and 1 atmosphere)
20 psi = 555.85 inH2O @39.2 F
30,000 feet per hour = 5.68 miles per hour.
scfh is "standard cubic feet per hour" and cfh doesn't neccessarily mean "standard". Standard conditions are stanard temperature (293 K), and standard pressure (1 atm, 101,300 Pa).
