The following calculator can be used to calculate the header dimensions best suited to your combination. If you have a custom material, you can enter your own value for the co-efficent of thermal expansion. If you are attaching ductwork to the exhaust side of your dust collector it is accepted practice to use a duct diameter two inches larger on the exhaust side than on the inlet side, thus. Then pipe size equals the square root of the previously calculated c/s area times the reciprocal of the constant 0. Pipe network can simulate city water system pipe networks, car exhaust manifolds, long pipeline networks with different diameter pipes in series, parallel pipes, groundwater flow into a slotted well screen, soil vapor extraction well design, and more. Tube diameter is really important. The exhaust pipe works because of the pressure waves generated when the exhaust valve opens. • A chimney that is too short may produce insufficient draft (drawing of air). For a street engine, it is recommended to tune pipe dimensions to peak torque rpm (usually 3,000-4,000 rpm). " Test 1: Open Exhaust Step one involved jerking off the Chevelle's cobbled-together dual exhaust system and running open. Internal Diameter Sizing Calculations for a given flow and pressure. The Pipe Flow Wizard Software calculates the type of flow that will occur in the pipe (laminar flow or turbulent flow), the Reynold's number, the friction factor and the fluid velocity, to derive a minimum size for the internal diameter of the pipe.

Calculation: From Table 1, carbon steel pipe expansion 220°F (104°C) 1. Exhaust system components such as mufflers and exhaust tips normally use inner-diameter dimensions on the piping used to build these components. Generally it’s recommended to get a 6” for most setups, since most air-cooled hoods and ducting have a 6” opening. A smaller pipe diameter will produce higher exhaust velocities at a lower RPM but create unacceptably high amounts of back pressure at high rpm. Or the smallest diameter exhaust possible without cutting the volume down to much and creating backpressure issues. Walk in prices may be higher.
