* 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. ...
A portable, non-invasive flowmeter for a partially filled pipe includes a Doppler shift velocity sensor and a level sensor, each of which has an ultrasonic transducer which is releasably attached to the outside of the pipe out of communication with the interior thereof. The transducers are coupl...
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...
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 ...
The full description of the simulation setup is given in Zirwes et al. (2020). Here, the simulation setup is described briefly. In configuration FJ-5GP-Lr75-57 (Barlow et al.2015) of the Sydney/Sandia flame, the central fuel pipe is retracted by 7.5 cm, thus creating compositionally in...
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...
In addition, it was found that temperature history analysis based on heat conduction calculations is effective in predicting the optimum mandrel position, which varies depending on molding conditions. These results provide a guideline for high-speed pultrusion molding.Toshihiro Motochika...

This value visualizes how much the relative consumption can—according to the measurements and assuming a Gaussian distribution—differ from the average value that is used for the calculations in this paper. Furthermore, this deviation is propagated in order to estimate how much the consumption ...
