Units of n are often omitted, however n is not dimensionless, having dimension of T/L 1/3 and units of s/m 1/3. R h is the hydraulic radius (L; ft, m); S is the stream slope or hydraulic gradient , the linear hydraulic head loss loss (dimension of L/L, units of m/m or ft/ft); it is the same as the channel bed slope when the water depth is constant.
In seafaring, under keel clearance (UKC) is the height between seabed and the keel or hull of a ship. [ 1 ] [ 2 ] [ 3 ] It is used to ensure sufficient navigable water is available for ships at sea. [ 4 ] [ 5 ] [ 1 ] [ 6 ] It is most commonly defied as Master mariners should ensure there is sufficient minimum UKC for their ships ; ports should ...
Used mainly to determine the minimum water depth for safe passage of a vessel and to calculate the vessel's displacement (obtained from ship's stability tables) so as to determine the mass of cargo on board. Draft, Air – Air Draft/Draught is the distance from the water line to the highest point on a ship (including antennas) while it is ...
In Canada, steel I-beams are now commonly specified using the depth and weight of the beam in metric terms. For example, a "W250x33" beam is approximately 250 millimetres (9.8 in) in depth (height of the I-beam from the outer face of one flange to the outer face of the other flange) and weighs approximately 33 kg/m (22 lb/ft; 67 lb/yd).

The use of the depth–slope product — in computing the bed shear-stress — specifically refers to two assumptions that are widely applicable to natural river channels: that the angle of the channel from horizontal is small enough that it can be approximated as the slope by the small-angle formula, and that the channel is much wider than it is deep, and sidewall effects can be ignored.
In the following equations, denotes the sagitta (the depth or height of the arc), equals the radius of the circle, and the length of the chord spanning the base of the arc. As 1 2 l {\displaystyle {\tfrac {1}{2}}l} and r − s {\displaystyle r-s} are two sides of a right triangle with r {\displaystyle r} as the hypotenuse , the Pythagorean ...
A California woman was fatally shot by her 2-year-old toddler, leading to the arrest of her boyfriend who is accused of failing to properly store the weapon, Fresno police said this week.
The U.S Capitol is seen after U.S, President-elect Donald Trump called on U.S. lawmakers to reject a stopgap bill to keep the government funded past Friday, raising the likelihood of a partial ...
