* Be able to calculate the normal depth for a specified flow rate of water through a pipe of known diameter, slope, and full pipe Manning roughness coefficient.* Be able to carry out the calculations in the above learning objectives using either U.S. units or S.I. units.Harlan H. ...
The diagram at the right shows the parameters used in partially full pipe flow calculations when the flow depth is less than the pipe radius. K is the circular segment area; h is the circular segment height; S is the circular segment arc length; θ is the central an...
Referring to FIGS. 1 and 2, there is illustrated a generally horizontally disposed closed pipe or conduit 10 having a circularly cylindrical wall 11 and partially filled with a liquid 15 to a surface level 16. The liquid 15 is flowing in a direction indicated by the arrow and may contain e...
The pressure drop simulated data obtained by FLUENT® for the cases experimentally studied here, in fully developed flow conditions, have been compared with the predictions from a recently introduced model which covers the full flow regimes in annuli, proposed by Kelessidis et al. (2006). The...
A combination of FEM and the boundary element method can deal with such problems by considering the half-space Green's function [19,20], but the frequency band used in the calculations is limited due to the dramatically increased computational cost. For simplicity, Amabili [21,22] and Ergin...
e.g. for complex geometries which do not allow the use of higher order discretization schemes, but is accurate enough so that the results of a full DNS are expected to be similar. In the context of this work, the quasi-DNS resolves the flow field down to the Kolmogorov length and fully...
A desired location of the water level measurement point for flow rate calculations was provided. Discharge curves were identified for three sharp-crested weirs of 0.0465, 0.0634 and 0.0771 m in height, installed in the pipe of 0.1534 m in diameter and inclinations of 0.5 and ...
The author is commended on developing explicit analytical equations that enable the flow problems in partially filled circular pipes to be solved without iterative calculations. This discussion focuses on the variation of the Manning roughness coefficient with flow depth and compares the values from four...
The simulation of a turbulent swirling flow, however, is a challenging task, and accurate numerical calculations of the flow parameters require a careful choice of turbulence closure method. Several previous turbulent swirling flow predictions have been carried out employing the steady Reynolds-averaged ...
Accordingly, underestimating the required pump flow does not lead to a full stop of the actuator with the highest load pressure as it would in a system with pre-compensated valves. 2.4.2. Pump-Controlled Boom for the Improved Setup To obtain the actual setup of interest, the reference setup...
