How do you size the vent pipe in terms of total quantity of fixtures?

Well the UPC (uniform Plumbing code) has the information but your drain line going outside the building and your vent line going outside the roof has to meet the same square inches. So if you have a main dran line that is 4" running outside the building then your must have enough square inches of pipe going threw the roof in example ( you would need four 2" vent pipes to equal one 4" pipe). Trailer homes don't follow the code and they go by the AWC (almost works code)

How do you compute the pipe length?
minus weld gaps and takeoffs from total then multiply for angle.
Area of pipe when thickness of wall inner radius of pipe and length of pipe is given?
For a pipe of uniform radius and thickness, I believe the total surface area would be the Outside surface + Inside surface+ 2 times the surface of the ends. The inside radius(rinner), pipe thickness (t), and pipe length (L) are given.So you only need to find the outside radius (Rout) and then all areas can be calculated.The outside radius should be Rout=rinner +t. And note the perimeter of a circle is 2*pi*Radius and area of an annular region (in this case the ends of the pipe) is A= pi*(Rout2 - rinner2)For the outer pipe surface: Aout=2*pi*(Rout)*LFor the inner pipe surface: Ainner=2*pi*(rinner)*LFor each pipe end: Aend= pi*(Rout2 - rinner2)So the total surface area of the pipe would be: Aout+ Ainner+2* AendOr: Atotal =2*pi*(Rout)*L+2*pi*(rinner)*L+ 2*pi*(Rout2-rinner2)= pi*[ 2*L*(Rout + rinner)]+(Rout2 - rinner2)= 2*pi*[ L*( rinner +t + rinner)]+(( rinner +t )2 - rinner2)]=2*pi*(t+L)(t+2*rinner)Hopefully that is correct and helps.

What is the difference between 1.5D pipe bend and 5D pipe bend?

How do you calculate the surface area of pipe fitting?
To calculate the surface area of a pipe fitting, you need to use the formula 3.14 x L x D. The L stands for the length of the pipe and the D is the diameter of the pipe.
What is bend pipe?
pipe bending is a method to enhance the fabrication capabilities of pipe work and plumbing fixtures
Why is it necessary to lay out and calculate the length of pipe required for a job?

How many fixtures can1.5 inch pipe vent?
That would depend on the fixture units each fixture has and the developed length of the vent piping
Do you connect a downstairs toilet to an existing stench pipe or go straight into the drain?
It depends on the configuration of the pipe. It must be a minimum of 3" pipe and the configuration of how it is hooked up must allow for the toilet to be vented and must not disrupt the venting of other fixtures. Call a plumber.
Can you use plumbers putty with plastic pipes or marble fixtures?
Oils from putty soak into and discolor marble. Putty not used when putting pipe together.
When the washer drains it sucks the water out of the toilet?
Sounds like your washer doesn't have a connection to your "stack pipe". As water moves through a drain pipe, it creates a vacuum behind it, the "stack pipe" or "vent pipe" is usually a pipe that goes through the roof of your house and provides an open air connection to all of your plumbing fixtures so the vacuum is provided a way to suck air rather than sucking the water out of your "P" traps or other fixtures such as your toilet. Chances are your toilet is also "sucking" from your washer, but you just don't notice it. It is also dangerous because if the washer or other fixtures are sucking water out of your "P" traps, then you may be getting methane and other sewer gases into your house. Have a pipe run from washer drain to your vent pipe and this should eliminate the problem. Be sure it connects to the vent pipe because if you ever have a sewer backup, the vent system won't allow the gray water to empty into your house through the air pipe.
How do you find out water velocity in pipe?
Hello, Velocity in a pipe is the flow divided by the area. If the pipe is full, the area is simply pi*r². Here is a useful calulator for full pipes: http://www.tasonline.co.za/toolbox/pipe/velocity.htm
What is the maximum water carrying capacity of 7 inches diameter pipe?
In terms of volume: infinite - there is no limit to how long the pipe can be!
In an older house if you have the metal pipe for the toilet without a flange in the basement can you split the pipe and add the flange to use it for a sink drain too?
Install a ty fitting on the stack in the basement then run it to the sink. Put it low enough to account for a fall in the pipe, to allow proper drainage. Be sure to install a waste and vent pipe to code for both fixtures.
