Wave-making resistance is a form of drag that affects surface watercraft, such as boats and ships, and reflects the energy required to push the water out of the way of the hull. The hull of a moving watercraft creates waves (a wake ) which carry energy away and resist the motion of the watercraft.
where constant (k) should be taken as: 2.43 for velocity (V) in kn and length (L) in metres (m) or, 1.34 for velocity (V) in kn and length (L) in feet (ft). Observing this, Froude realized that the ship resistance problem had to be broken into two different parts: residuary resistance (mainly wave making resistance) and frictional resistance.
Salt displace to the top and is cut off from the source layer Right lateral shear, salt layer is marked in blue: 2 Preexisting Localized extension Widening of diapir, diapir can fall if the rate of salt supply is not enough to support the weight of the overlying rock, [16] but will rise if there is sufficient salt supply to push up the ...
Buoyancy (/ ˈ b ɔɪ ən s i, ˈ b uː j ən s i /), [1] [2] or upthrust is a net upward force exerted by a fluid that opposes the weight of a partially or fully immersed object. In a column of fluid, pressure increases with depth as a result of the weight of the overlying fluid. Thus, the pressure at the bottom of a column of fluid is greater ...
Ship stability illustration explaining the stable and unstable dynamics of buoyancy (B), center of buoyancy (CB), center of gravity (CG), and weight (W) Ship stability is an area of naval architecture and ship design that deals with how a ship behaves at sea, both in still water and in waves, whether intact or damaged.

If your scale says your weight went up overnight, you might wonder: Can you gain weight in one day? Experts give 11 reasons you seemed to gain weight overnight.
Molten FLiBe (2LiF·BeF 2). Molten salt is salt which is solid at standard temperature and pressure but liquified due to elevated temperature. A salt that is liquid even at standard temperature and pressure is usually called a room-temperature ionic liquid, and molten salts are technically a class of ionic liquids.
