  2. Drawdown (hydrology) - Wikipedia

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

    It is the height of the free surface of water above a given point beneath the surface. [4] Pumping level is the level of water in the well during pumping. [8] Specific capacity is the well yield per unit of drawdown. [8] Static level is the level of water in the well when no water is being removed from the well by pumping. [8]

    This diagram illustrates the three different heads (hydraulic, pressure and elevation) for hydrostatic (no flow) conditions. The yellow rectangle represents a sand and water filled tube or column with its top open to the atmosphere and its bottom drained by a pipe or tube (blue line).

  5. Maxwell construction - Wikipedia

    en.wikipedia.org/wiki/Maxwell_construction

    The discontinuity in , and other properties, e.g. internal energy, , and entropy,, of the substance, is called a first order phase transition. [12] [13] In order to specify the unique experimentally observed pressure, (), at which it occurs another thermodynamic condition is required, for from Fig.1 it could clearly occur for any pressure in the range .

  6. Shell balance - Wikipedia

    en.wikipedia.org/wiki/Shell_Balance

    The balance is determining what goes into and out of the shell. Momentum is created within the shell through fluid entering and leaving the shell and by shear stress. In addition, there are pressure and gravitational forces on the shell. From this, it is possible to find a velocity for any point across the flow.

  7. Hydraulic jumps in rectangular channels - Wikipedia

    en.wikipedia.org/wiki/Hydraulic_Jumps_in...

    Hydraulic jump in a rectangular channel, also known as classical jump, is a natural phenomenon that occurs whenever flow changes from supercritical to subcritical flow. In this transition, the water surface rises abruptly, surface rollers are formed, intense mixing occurs, air is entrained, and often a large amount of energy is dissipated.

  8. Thermodynamic square - Wikipedia

    en.wikipedia.org/wiki/Thermodynamic_square

    G = Gibbs free energy p = Pressure H = Enthalpy S = Entropy U = Internal energy V = Volume F = Helmholtz free energy T = Temperature. The thermodynamic square (also known as the thermodynamic wheel, Guggenheim scheme or Born square) is a mnemonic diagram attributed to Max Born and used to help determine

    English: Diagram of torsion balance used in the Cavendish experiment performed by Henry Cavendish in 1798. It measured the force of gravity between masses M and m, yielding the value of the gravitational constant G. Labels: (M) mass of stationary lead balls, (m) mass of movable lead balls, (F) gravitational force between each pair of balls, angle of deflection of balance from equilibrium ...
