  2. Love number - Wikipedia

    en.wikipedia.org/wiki/Love_number

    Neutron stars are thought to have high rigidity in the crust, and thus a low Love number: ; [6] [7] isolated, nonrotating black holes in vacuum have vanishing Love numbers for all multipoles =. [ 8 ] [ 9 ] [ 10 ] Measuring the Love numbers of compact objects in binary mergers is a key goal of gravitational-wave astronomy .

  3. Static pressure - Wikipedia

    en.wikipedia.org/wiki/Static_pressure

    At least one author takes a different approach in order to avoid a need for the expression freestream static pressure. Gracey has written "The static pressure is the atmospheric pressure at the flight level of the aircraft". [15] [16] Gracey then refers to the air pressure at any point close to the aircraft as the local static pressure.

  4. Pressure head - Wikipedia

    en.wikipedia.org/wiki/Pressure_head

    This is why static pressure and dynamic pressure are never the same in a system in which the fluid is in motion. This pressure difference arises from a change in fluid velocity that produces velocity head, which is a term of the Bernoulli equation that is zero when there is no bulk motion of the fluid. In the picture on the right, the pressure ...

  5. Flow conditions - Wikipedia

    en.wikipedia.org/wiki/Flow_conditions

    In fluid measurement, the fluid's flow conditions (or flowing conditions) refer to quantities like temperature and static pressure of the metered substance.The flowing conditions are required data in order to calculate the density of the fluid at flowing conditions.

  6. Diffuser (thermodynamics) - Wikipedia

    en.wikipedia.org/wiki/Diffuser_(thermodynamics)

    A diffuser is "a device for reducing the velocity and increasing the static pressure of a fluid passing through a system”. [1] The fluid's static pressure rise as it passes through a duct is commonly referred to as pressure recovery. In contrast, a nozzle is used to increase the discharge velocity and lower the pressure of a fluid passing ...

  8. Hand boiler - Wikipedia

    en.wikipedia.org/wiki/Hand_boiler

    A hand boiler or (less commonly) love meter is a glass sculpture used as an experimental tool to demonstrate vapour-liquid equilibrium, or as a collector's item to whimsically "measure love." It consists of a lower bulb containing a volatile liquid and a mixture of gases that is connected usually by a twisting glass tube that connects to an ...
