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
1 mmcfh = 1,000 mcfh = 1,000,000 scfh
110 - 130 Scfn is what in psi
divide by 60
times 60
1 cfh = 1 mbh
Equal in what way?

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
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).
30,000 feet per hour = 5.68 miles per hour.
