Basic Math for Plumbing

This math video covers basic math for plumbing. Includes explanation about length, area, volume, cubic feet. cubic yards and PSI. Contractor License Center specializes in training Contractors to pass the state contractor licensing exams through our exam preparation services. Our top contractor schools will show you the ins and outs of each subject matter of the contractor testing.

Thanks! I’m going through an early life crisis and need a good career to establish life

Same here

Me too bro

[@cattlecooker953]

Right? Aha I’m just approaching the last of my twenties and all that partying and making friends really led me to fuck all career wise. No foundation and I just wanna have some comfort knowing I have something to fall back on.

@@cattlecooker953 I’m 21 and idk have a lot of issues. Let’s start with my gf comparing what we have to other people such as an exxxxx. Yeahhhhh need to get my ducks in a row. Not because my girl is basically comparing what I have to her ex. But because at anytime ong I might have to dip and have ambitions too. Goals. Idk I’ve been a bum doing fuckin housekeeping the past 4 years because I was a late bloomer for my license so I got a job with my mother and carpooled out of convenience. Now I feel like I’m completely fucked

@@theindustryfarm7405 if she’s comparing you to your ex just leave her alone, trust me that’ll continue to be a problem even if you mention you have a problem and ask her to stop odds are she’ll grow resentment and label you as “controlling” and continue to look for other meat while stringing you along as a “back up”

I start the math class tomorrow and this flicked a lightbulb for me.

thank you

Great !!!

1.414 for 45 degree offsets is right but .414 for 22 1/2 degree offsets is wrong.

[@gregbowman9646]

These numbers come from the "Mathematics for Plumbers and Pipefitters" book.

[@anthonymonah7116]

1.414 is the square root of 2. To find the travel of a 22 1/2 degree offset, multiply by 2.61

[@ContractorLicenseCenterVideos]

.414 is NOT for the diagonal (like the constant 1.414 is for a 45*) but rather for the OFFSET of 22.5* (.414 is the tangent of 22.5) Source: Mathematics for Plumbers and Pipefitters, Appendix 283 Constants for 22 1/2 degree fittings and Data 25 Constants for Parallel Offsets

[@anthonymonah7116]

I did my five year apprenticeship at Plumbers Union local One in NYC. We never did tangents, we always did travel, advance or offset. Many years ago when bell and spigot was popular plumbers had to know all kind of formulas but now we use nohub pipe.Down to 1/4 bends, 1/8 bends and 1/16 bends or 1/5 and 1/6 bends for rolling offsets once in a blue moon. The only time we use a 22 1/2 degree offset is fitting to fitting. By the way the video was very interesting.@@ContractorLicenseCenterVideos

@@anthonymonah7116 He says .414 to find the OFFSET, you're calculating the travel which is the offset multiplied by 2.61. For a 45 degree the offset and the advance are the same, but for 22.5 degrees the offset and travel are different. It's trigonometry you should learn.
