1. An electro-hydraulic converter for varying the hydraulic resistance of liquid in a pressure pipe section, comprising a housing with inlet and outlet branch pipes; said housing being the outer electrode of the converter, the inner electrode being accomodated inside said housing; a D.C. source...
Pressure in a pipe system can be calculated using the equation P = F/A, where P is the pressure (in psi or kPa), F is the force exerted by the fluid (in pounds or newtons), and A is the cross-sectional area of the pipe (in square inches or square meters). What factors a...

i.e. i m solving the Pressure Poisson Equation and so I got the non-linear term and as did what I mentioned in my previous posting. To check the correctness of my code, I applied the boundary condition for simple pipe flow. I am in process to check whether the code is diverging afte...
The internal fluid is considered as a one-dimensional flow when the pipe diameter is less than 1/5 of the pulsation wavelength [4] in the above analysis methods. When such an assumption is not applicable, the boundary element method, which is used in the field of acoustics, can be ...
To distinguish whether the flow in a pipe is laminar or turbulent, Reynold's criterion may be used. It states that for laminar flow, the Reynold's number should be smaller than 2320. The Hagen鈥揚oiseuille equation is derived and illustrated in the chapter. For turbulent flow, an equation...
Liquid Pressure Drop in Pipe and Pipe Fittings Spreadsheet Calculator. For the calculation of the friction factor the worksheet uses the Haaland equation which gives an implicit solution to the friction factor.
and the length of the pipe. This equation is valid for all fluids in both laminar and turbulent flow. The disadvantage is that the Darcy- Weisbach friction factor is a variable. J = ( f .L.v² ) / 2.g.D where, J = Head loss, m g = Gravity constant, 9.81 m/s² v = ...
With a schedule 40 pipe, this outlet pipe would require a DN65 (3 in.) pipe which is the next standard size up. If it is not possible to reduce the backpressure to below 10% of the set pressure, a balanced bellows or pilot-operated SRV should be considered. Ideally, SRVs installed ...
were used to describe the pressure profile, which is significantly dependent on the longitudinal stress relaxation behavior of the bandage, using the modified Laplace’s lawequation. QLV theory was also used to describe the relaxation behavior of the bandage at different level of strains. In the ...
