WebFeb 11, 2024 · It is used to transport materials such as natural gas, oil, water, wastewater, chemicals and other products. This type of transportation is considered to be energy and cost-efficient, as it is faster, safer and more reliable than road or rail transport. In some regions, pipelines are used to transport food items as well as hazardous materials. WebSince gas throughput is the same in both pumps (Roots pump and backing pump), the following applies: \[S_1=\frac{S_V \cdot p_v}{p_v \cdot \Delta p_d}\] Formula 2-5: Pumping speed of Roots pumping station with overflow valve open and at high fore-vacuum pressure
WebExample 2: If the effective pumping speed is 250 liter/sec and we wish to inject 0.1 torrliters per second flow of gas (and let's assume this is the total gas load or throughput) the steady state pressure in the chamber is: 0.1 / 250 torr = 4 x 10-4 torr.
