All formulas for finding the amount of water that will flow through a pipe in a given time are approximate. The formula that follows will give results within 5 or 10 per cent of actual flows, if applied to pipe lines carefully laid and in fair condition. Vfps= V · 0.7854 Le= [ ( ...
To find the velocity head of water flowing in a horizontal pipe, we can use the formula for kinetic energy per unit volume, which is related to the velocity head. The velocity head (h) can be calculated using the following steps:1. Iden
I plotted the velocity magnitude across the center of the pipe and got the results shown in the graph below.I'm hoping someone can clue me in to an explanation the various behaviours. Namely:1. Why is there such a big difference between the Kw and KE profiles at 8 ft/s?...

One way to find the pressure difference between the ends of a pipe is to use theDarcy-Weisbachequation I mentioned in part 1. This predicts how much pressure would be needed to push the water along a pipe at a particular speed. The formula looks like this: ...
This observation was almost certainly a result of the transfer of axial momentum from the less dense dispersed phases to the water, which occurred preferentially at the pipe centre. For upward inclined multiphase flows RT#1 was found to give rise to water velocity profiles which are more ...
Calculate the volumetric flow rate of water for the pipe shown. Answer: Q = 2.46 x 10-5 m3 / s Volumetric flow rate for incompressible fluids is {eq}Q=A_1v_1=A_2v_2 {/eq} Bernoulli's equation is given by {eq}\frac{p_1}{\rho g}+\frac{v_1^2}{...
The velocity of sound in water was measured up to 700°C and 300 MPa. A classical pulse method has been used. The frequency was typically 5 MHz. The mean accuracy of the data is 0.5% of the velocity. The greatest error in velocity is due to the uncertainty in the temperature measuremen...
