Science / Tides and Currents / K2: Lunisolar semi diurnal constituent. This constituent modulates the amplitude and frequency of M2 and S2 for the declinational effect of the Moon and Sun, respectively. Speed = 2T + 2h = 30.082,137,3° per solar hour.

Wk2 (Moment Of Inertia)

Technology / Motors / Wk2 (Moment Of Inertia): The moment of inertia is expressed as Wk2or WR2in terms of pound-feet squared. It is the product of the weight of the object in pounds and the square of the radius of gyration in feet. If the applicat MORE

Lunisolar Tides

Science / Tides and Currents / Lunisolar Tides: Harmonic tidal constituents K1, and K2, which are derived partly from the development of the lunar tide and partly from the solar tide, the constituent speeds being the same in both cases. Also, the l MORE

Low Water Equinoctial Springs

Science / Tides and Currents / Low Water Equinoctial Springs: Low water springs near the times of the equinoxes. Expressed in terms of the harmonic constants, it is an elevation depressed below mean sea level by an amount equal to the sum of the amplitudes of th MORE

Potassium (K)

Science / Periodic Table of Elements / Potassium (K): Atomic number: 19, Atomic mass: 39.0983 g.mol -1, Electronegativity: 0.8, Density: 0.86 g.cm -3 at 0 °C, Melting point: 63.2 °C, Boiling point: 760 °C, Vanderwaals radius: 0.235 nm, Ionic radius: 0 MORE


Business / Agriculture / Fertilizer: Any organic or inorganic material, either natural or synthetic, used to supply elements (such as nitrogen (N), phosphate (P2O5), and potash (K2O)) essential for plant growth. If used in excess or atta MORE
