a calculation problem
Thread Content
The pump outlet parameters and conditions are constant. The flow rate through the L-long pipe to point A is 22t/h (point A is directly connected to the atmosphere). The flow rate is 7t/h through the L+M long pipe to point A (point A is directly connected to the atmosphere). Then what is the flow rate when it reaches A through the L+M long pipe (the relative pressure of A is -4 KPa)? (The pipe is a DN50 cast iron pipe, the liquid density is 1.81)
Check the pipeline resistance coefficient for conversion, calculate the actual clean water lift, and check the flow rate from the pump's working curve.
It is recommended to check out "Principles of Chemical Engineering" to review the past and learn the new.
Check the working curve of the pump and the flow rate is about 15T.
