Fine. In real life, a centrifugal pump does not work like that, it needs to gain pressure, it is first launched onto a closed valve and then it is slowly opened to equalize the pressure, so the outlet pressure can be, for example, 10 MPa.<\/span><\/span><\/span><\/p>\n<p><span class=\"HwtZe\" lang=\"en\"><span class=\"jCAhz ChMk0b\"><span class=\"ryNqvb\"> So how can I carry out such a trick? My pump produces a nominal output of 500 m3\/day. Can I set the inlet flow and mute the outlet? Then I will look at the graph of the pressure in the pump cavity, when the pressure increases, I will stop the calculation and increase the outlet diameter each time, for example 0, 10, 50 and 100 mm &#8211; this is the desired diameter.
