The positive integer factors of 421 are: 1, 421
421 rounded to nearest tens is 420
421 is an integer and there is no sensible way to express it as a fraction.
420
421 is a prime number, so its only factors are 1 and itself.
Kw x 3412 / 10000 = gpm I think
You need to know the linear density.
Multiply gpm by the number of minutes the flow lasted, to find the gallons of volume that flowed during that time.
1TR= 12mbh 1gpm= 2.4tr 1gpm=28.8mbh
Multiply your gpm by 60.
There are BPM Software vendors that have this functionality embedded. One of them that I can think of is PNMsoft that has an integration with System Architect
First you need the size of the pipe and the volume of water supply. Pressure will vary during usage. Standard well system operates between 20-40 psi and city systems operate from 50-70 psi.
A fixture unit is 1 cubic foot of water (7.48 gallons) If your using pumped drainage /soil system then for every GPM of flow rate one has to consider it as ONE FU
52 gpm
gallon per minute (gpm).
7.48 Gal (1 CU FT) = 1 FU Or 1 GPM of pumped drainage = 1 FU The above equation that was submitted makes no sense whatsoever. Conversion of Fixture Units to gpm is non-linear; gpm per FU decreases as the total number of FU increases. I am a civil engineer, not mechanical engineer, but I know there are resources available either through International or local building codes that guide the designer.
2650 gph = 44.167 gpm
