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)
What else can I help you with?
How many fixture units in a 4inch horizontal pipe?
The number of fixture units that a 4-inch horizontal pipe can accommodate varies based on plumbing codes and the type of fixtures connected. Generally, a 4-inch pipe can handle around 40 to 50 fixture units, depending on factors like the length of the pipe and the specific code provisions in your area. To get an accurate assessment, it's best to consult local plumbing codes or a plumbing engineer.
How do you compute the pipe length?
minus weld gaps and takeoffs from total then multiply for angle.
How do you calculate the surface area of pipe fitting?
To calculate the surface area of a pipe fitting, you need to first determine the individual shapes that make up the fitting, such as cylinders, cones, or spheres. Then, calculate the surface area of each shape using the appropriate formulas (e.g., for a cylinder, the formula is 2πrh + 2πr^2). Finally, sum up the surface areas of all the individual shapes to get the total surface area of the pipe fitting.
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.
How do you layout any lateral on pipe?
drawing for lateral 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?
The length of pipe is required to be known to help procure the required quantity of pipe.
How many thick 20mm pipe?
To determine how many thick 20mm pipes you need, additional information is required, such as the total length of pipe needed or the specific application. If you provide that context, I can help you calculate the quantity. Otherwise, a single pipe with a diameter of 20mm is just one unit, regardless of thickness.
What is a nipple in plumbing and how is it used in the installation of pipes and fixtures?
In plumbing, a nipple is a short piece of pipe with threads on both ends. It is used to connect two fittings or fixtures together. Nipples are commonly used in plumbing installations to extend or connect pipes and fixtures in a tight space.
Is it important to know if the plumbing fixtures are flush valve or flush tank when calculating water supply pipe sizes?
yes
What is the function of Suction valve?
the suction valve is transfered fluid one pipe to another pipe at a specific pressure and quantity.
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.
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
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.
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!
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
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.
