A pipeline is a system of connected pipes for the transportation of liquids, gasses, and slurries. Slurries are fine solid particles suspended in a liquid. Pumps, valves, and other control devices control the flow. Products may be stored temporarily in storage tanks. Pipelines inside the facilities are usually suspended from the ceiling.

There are many equations for determining the flow in natural gas pipes and the pressure drops associated with those flows, or vice versa. Our intent is to determine the validity of each equation with respect to flow rates that might be encountered by a plumbing engineer. Previous articles in this series suggest that either schedule 40 steel pipe or …

Pneumatic conveying is the movement of solids through pipe using gas (usually air) as the motive force. It differs from hydraulic or slurry conveying in that the gas expands continuously along the pipe length. The flow regime in the pipe depends greatly on the ratio of solids to gas and the particle characteristics. Why use pneumatic conveying to.

The SI unit of flow rate is m 3 /s, but other rates can be used, such as L/min. Flow rate and velocity are related by Q = Av where A is the cross-sectional area of the flow and v is its average velocity. The equation of continuity states that for an incompressible fluid, the mass flowing into a pipe must equal the mass flowing out of the pipe.

Conservation of energy tells you that the pressure in the reduced area will be lower because the velocity is increased (speeding a fluid up lowers it pressure, some what counter intuitive because we think of pressure in terms of force not potential energy) Flow rate (Q) = velocity * Area.
