While the change in the roughness coefficient of the material used for the pipes will cause a decrease in the Total Pressure of about 42.6%, without Surge tank, and of 12.2% with Surge Tank. Nomenclature a Speed of pressure wave (m/s) C Roughness coefficient CD Complex device D Pipe ...
In this study, transient pressure in piped liquid due to waterhammer is a function of structural restraint at elbows. To study the effect of this phenomenon on polyethylene elbowed pipe networks, experimental tests were performed on polyethylene bent pipes, either in the absence or presence of a...
observed with magnetite are largely due to its magnetic properties, and some have speculated that the mass of ferromagnetic magnetite sand material in a MEOW kettle, along with the Earth's magnetic field, somehow induces a "magnetic vortex" inside the bottle of water inserted into such a kettle...

Aside from the roomtones, each hab has soft little sounds that play from all the machines, terminals, pipes, vents, generators, fans, etc. to make the ships feel more lived in. The attenuations on all the soft little sounds are kept pretty tight to make the space feel intimate as you...

The PDMS/glass bonding chip provides a miniaturized, cheap, and disposable material for pathogen diagnosis. The homemade thermal control module integrated with two cartridge heaters and one Peltier element supports the denaturation, extension, and annealing regions created inside the chip. Due to the ...
Water HammerFluid-structure interaction is an important topic for modeling water hammer pressure surges in piping systems. Even if recently, in technical literature there are many interesting contributes on water hammer propagation in viscoelastic pipes, little attention has been devoted so far to the ...
