Hello, I calculate minor losses in fittings using coefficient of resistance and data provided by the dealer.
If I have mechanical fitting such as this 90 deg elbow
The total minor loss is only 1x elbow (coef 1.2) or 1x elbow (1.2) + 2x connection (0.3 for d75)?
Do I have to count the...
yes they are centrifugal pumps. The system should feed another technology which needs 8-10 m3/h flow and 4 bar pressure at its inlet.
First pump PSP 18-22
Second pump Ebara Matrix 10-5
This is the system curve from the first pump to the suction of the second. The Q will be 12 m3/h, which is...
Hello, I have a general question regarding 2 different pumps in series.
In this situation the head is added and flow remains the same Q = Q pump1 = Q pump2.
Also I read if the capacities of the pumps are different the flow is determided by the smallest pump.
But in practical situation , what...
