WebNov 5, 2024 · Flow is proportional to pressure difference and inversely proportional to resistance: (14.S.20) Q = p − 2 p 1 R. The pressure drop caused by flow and resistance is given by p 2 – p 1 = RQ. The Reynolds number N R can reveal whether flow is laminar or turbulent. It is N R = 2 ρ v r η. For N R below about 2000, flow is laminar. WebThe flow work is the work done on the system when entering material is pushed into it or the work done by the system when the system pushes the material out of the system. In …

The shaft work and 2. The work to push fluid into and out of the control volume. …
WebMay 22, 2024 · In this equation the term Vdp is a flow process work. This work, Vdp, is used for open flow systems like a turbine or a pump in which there is a “dp”, i.e. change in pressure. There are no changes in control volume. As can be seen, this form of the law simplifies the description of energy transfer.
