What is a fuel return pipe?
The fuel return hose is a fuel system hose that is found on vehicles equipped with carburetors. Aside from providing a path for excess fuel to return to the tank, the fuel return hose also prevents vapor lock and over pressurization from occurring within the carburetor.
How to calculate the flow rate of a gas pipe?
Example 2: A rectangular pipe has a height of 2cm and width of 4cm and a gas running through it at a speed of 15 m/s. What is the discharge rate of this pipe? First, we find the cross-section area which is simply 2 · 4 = 8 cm 2 or 0.0008 m 2. To find the flow rate Q, we multiply 0.0008 by 15 to get 0.012 cubic meters per second.
When does the pressure on a gas pipe reach its maximum?
When the pressure on the downstream of the gas flow reaches certain value, further pressure decrease at the end will not cause higher weight rate of flow [kg/s]. It means that the gas flow in the pipe has its maximum depending on the available energy on beginning.
What happens when you have a fuel pipe blockage?
A total blockage will stop the car, but a partial one may only cause fuel starvation at high speed, which is hard to diagnose as there may be other causes. One clue is that the effect is often spasmodic. If you suspect a blockage, the quickest way to check is to free both ends of the pipe and blow through it.
What should I do when I check the fuel pipes?
Whenever you check fuel pipes, disconnect the battery to prevent stray sparks igniting petrol or petrol vapour. Above all, put out all naked lights and cigarettes. Use a torch rather than an inspection lamp, which could start a fire if the bulb is accidentally broken.

Why is gas coming out of the overflow tube?
When the fuel is turned on gas starts coming out of the overflow tube. It doesn’t matter if the engine is running or not. The bike will start and run like there is nothing wrong. But, the gas is dripping severly out of that tube. The bike is a 2001 Yamaha YZ 125, we bought it used about 5 months ago and have no idea how many hours are on it.
Is the incompressible flow assumption valid for gas pipe?
Comments on gas flow As mentioned above, the equations that our pipe flow calculator is based upon are for incompressible flow. The incompressible flow assumption is valid for liquids. It is also valid for gases if the pressure drop is less than 40% of the upstream pressure.
