  2. Drawdown (hydrology) - Wikipedia

    en.wikipedia.org/wiki/Drawdown_(hydrology)

    In surface water hydrology and civil engineering, drawdown refers to the lowering of the surface elevation of a body of water, the water table, the piezometric surface, or the water surface of a well, as a result of the withdrawal of water. [1] In either case, drawdown is the change in hydraulic head or water level relative to the initial ...

  3. Standard step method - Wikipedia

    en.wikipedia.org/wiki/Standard_Step_Method

    The same logic applies downstream to determine that the water surface follows an M3 profile from the gate until the depth reaches the conjugate depth of the normal depth at which point a hydraulic jump forms to raise the water surface to the normal depth. Step 4: Use the Newton Raphson Method to solve the M1 and M3 surface water profiles. The ...

  4. Well test - Wikipedia

    en.wikipedia.org/wiki/Well_test

    Well testing differs from aquifer testing in that the behaviour of the well is primarily of concern in the former, while the characteristics of the aquifer (the geological formation or unit that supplies water to the well) are quantified in the latter. When water is pumped from a well the water level in the well falls. This fall is called ...

  6. Manufacturing process management - Wikipedia

    en.wikipedia.org/wiki/Manufacturing_process...

    Manufacturing process management (MPM) is a collection of technologies and methods used to define how products are to be manufactured. MPM differs from ERP/MRP which is used to plan the ordering of materials and other resources, set manufacturing schedules, and compile cost data.

  7. Watertable control - Wikipedia

    en.wikipedia.org/wiki/Watertable_control

    In geotechnical engineering, watertable control is the practice of controlling the height of the water table by drainage.Its main applications are in agricultural land (to improve the crop yield using agricultural drainage systems) and in cities to manage the extensive underground infrastructure that includes the foundations of large buildings, underground transit systems, and extensive ...

    en.wikipedia.org/wiki/Drawdown_chart

    Drawdown charts are rectangular pieces of non-fluorescent paper [1] which are used to test a variety of coating properties. These properties include opacity , spreading rate , penetration, and flow & leveling behavior. [ 2 ]

  9. Industrial water treatment - Wikipedia

    en.wikipedia.org/wiki/Industrial_water_treatment

    Water cooling is a method of heat removal from components of machinery and industrial equipment. Water may be a more efficient heat transfer fluid where air cooling is ineffective. In most occupied climates water offers the thermal conductivity advantages of a liquid with unusually high specific heat capacity and the option that of evaporative ...
