which are insensitive to density, pressure, and viscosity variations and are not affected by changes in the Reynolds number, should be kept in mind. Also underutilized in the chemical industry are the various flumes that can measure flow in partially full pipes and can pass large floating or ...
Average velocity is then obtained by multiplying the peak Doppler shift by a factor, for example, 0.90. In one embodiment, the transmit pulse and receive samples are interleaved by alternating between transmitting a pulse and, after a delay, sampling the received signal.Petroff, Alan M...

For partially full pipes, see Manning formula and use the hydraulic radius in place of the full flowing pipe area. https://en.m.wikipedia.org/wiki/Manning_formula For whatever formula you use, if downstream water level is higher than upstream, reverse your flow direction. Upstream becomes down...

The most obvious property of a porous material is that it partially occupies the volume that would otherwise be available to the fluid. This is quantified by defining the porosity ϕ of a particular porous medium, as the fraction of the overall volume that is occupied by the pores or voids...

[22] published their first paper describing flow in pipes with diameters ranging from 30 to 150 mm. In 1909, Knudsen et al. [23] studied gas flow through glass capillaries in transition and free molecular flow schemes. In 1913, Gaede et al. [24] conducted the first known parallel ...
