Apologies for the delay. - search is the most efficient way to navigate the Engineering ToolBox! Insults? Instead of running 1/2 inch copper flex with Ts to each appliance, do i need to increase the volume in the system to have enough gas to feed all three appliances.

Air-cooled generators are smaller and cost less, but they’re also louder than liquid-cooled models. You asserted that you’re asking just about pipe diameter and you don’t care about pressure, but it’s important to understand that it’s inadequate piping size (or improper regulators or regulator settings) that would deliver inadequate gas pressure (or flow rate in CFM per minute) at one or more appliances. If I was using NG, i'd install at least a ten foot piece of 1 1/4 black pipe to build up the volume and then run 1/2 inch Ts with 1/2 inch pipe to the appliances. 2.The pipe size of each section of branch piping not previously sized shall be determined using the length of piping from the point jwh,jr.

As you choose a higher and higher pressure high pressure propane regulator, the degree of control that the propane regulator valve has over the gas output decreases; i.e., turning the valve an 1/8" in a 0-60 psi adjustable propane regulator has a lot more effect than turning the valve an 1/8" in a 0-20 psi adjustable propane regulator. are all the different materials (coated flexible copper, alum, stainless steel) equal as far as safety and durability?
