Mass flow rate in pipeline
WebIn this zone of moderately high flow rate the fluid flows laterally within the pipe as well as in the primary direction although some laminar boundary layer outside the zone of roughness still exists. Starting in the left side of this region, flow is governed by the smooth pipe law of von Karman and Prandtl: WebIn this paper a PID controller is utilized in order to control the flow rate of the heavy-oil in pipelines by controlling the vibration in motor-pump. A torsional actuator is placed on the motor-pump in order to control the vibration on motor and consequently controlling the flow rates in pipelines. The necessary conditions for asymptotic stability of the proposed …

In electricity, the rate of flow of charge is electric current. Ver más Web10 de may. de 2024 · If we look at it from the point of view of qualitative analysis. The relationship between the pressure in the pipe and the flow rate is proportional. That is, the higher the pressure, the higher the flow rate. The flow rate is equal to the velocity multiplied by the cross section. For any section of the pipe, the pressure comes from only one end.
