Can you please tell how we got (pumping speed =757 m3/h) from the graph.
please provide a good explainations and show how we got this number 757 from the attached graph.
thank you

Design Criteria We have the char of density 1.59 g/cm (carbon), so the vacuum air velocity must be high enough to carry a particle the size of char. We can determined this with pipe diameter area which is (m/m). From the Fig1, we can also determine the requirement speed for the vacuum system then we can determine the selection for the vacuum pump. From the conveying velocity graph Fig1b, the phase should be around 20 m/s or more for velocity Pipe ID (m) 0.1 Cross Section (m2) 0.00785 Pumping Speed (m3/h) 757 Velocity (m/s) 27 Velocity (fpm) 5272
