Nitrogen flow rate calculation
Thread Content
The pressure in the nitrogen pipeline network is 0.5 MPa. Currently, a certain device is being pressurized (with an operating pressure of 0.2 MPa). The pipe diameter is DN50 and the length of the pipe is 100 m. Can the maximum nitrogen flow rate through this section of pipeline be calculated?
Could we consider using Bernoulli’s equation to do the calculation?
I suggest finding a book on Principles of Chemical Engineering to read; otherwise, you still lack many necessary prerequisites. Such as pipe material, elbows, valves, and data related to the resistance coefficient. Selection of flow rate.
It cannot be calculated, but in practice the supply capacity of the nitrogen pipeline network also needs to be taken into account; moreover, as pressure increases, the flow rate inevitably decreases, so such flow rate calculations have little practical significance
The maximum flow rate corresponds to a minimum pressure loss of 0.3 MPa; the minimum pressure loss occurs when the control valve is fully open. However, the pipe flow velocity also needs to be taken into consideration.
