During conventional hot plate welding, a successful joining phase depends on proper maintenance of squeeze flow to ensure that pressure and temperature create an ideal weld. Excessive pressure causes squeeze out of valuable material and weakens the bond due to fiber realignment in the melt layer, [ 7 ] while failure to allow cooling to room ...
A land mine can be triggered by a number of things including pressure, movement, sound, magnetism and vibration. [43] Anti-personnel mines commonly use the pressure of a person's foot as a trigger, but tripwires are also frequently employed. Because modern anti-vehicle mines usually employ magnetic triggers, they can detonate even if the victim ...
This high-pressure area is formed due to strong descending motion behind the squall line, and could come in the form of a downburst. [2] Outflow boundary that preceded a strong thunderstorm in Oklahoma. The "edge" of the outflow boundary can often be detected by Doppler radar (especially in clear air mode).
The boundary layer thickness, , is the distance normal to the wall to a point where the flow velocity has essentially reached the 'asymptotic' velocity, .Prior to the development of the Moment Method, the lack of an obvious method of defining the boundary layer thickness led much of the flow community in the later half of the 1900s to adopt the location , denoted as and given by
In non ideal fluid dynamics, the Hagen–Poiseuille equation, also known as the Hagen–Poiseuille law, Poiseuille law or Poiseuille equation, is a physical law that gives the pressure drop in an incompressible and Newtonian fluid in laminar flow flowing through a long cylindrical pipe of constant cross section.
Implosion is the collapse of an object into itself from a pressure differential or gravitational force. The opposite of explosion (which expands the volume), implosion reduces the volume occupied and concentrates matter and energy. Implosion involves a difference between internal (lower) and external (higher) pressure, or inward and outward ...
Hydraulic shoring is the use of hydraulic pistons that can be pumped outward until they press up against the trench walls. This is typically combined with steel plate or a special heavy plywood called Finform. Another method is called beam and plate, in which steel I-beams are driven into the ground and steel plates are slid in amongst them. A ...
The Z-pinch is an application of the Lorentz force, in which a current-carrying conductor in a magnetic field experiences a force.One example of the Lorentz force is that, if two parallel wires are carrying current in the same direction, the wires will be pulled toward each other.
