Principles of Chemical Engineering **Questions
Thread Content
I’m not very good at chemical engineering principles; I have a question and hope everyone can help explain it: if the flow rate remains constant and the pipe diameter is doubled, what will the pressure loss be? How to solve it specifically. Thanks
If the flow rate remains constant and the pipe diameter doubles, the flow velocity becomes 1/4. Based on the calculation of straight-pipe resistance: first, it is determined whether the flow pattern changes (i.e., the Re value); the resistance coefficient is then calculated using this Re value. In the case of laminar flow, the pressure loss becomes 1/8 of the original value. Turbulence will be calculated separately.
