Comparison of pumps. This article lists different types of pump and provides a comparison of certain key design features. Different types of pumps are suitable for different applications, for example: a pump's maximum lift height also determines the applications it can be used for. Low-lift pumps are only suitable for the pumping of surface ...
Clothing sizes are the sizes with which garments sold off-the-shelf are labeled. Sizing systems vary based on the country and the type of garment, such as dresses, tops, skirts, and trousers. There are three approaches: Body dimensions: The label states the range of body measurements for which the product was designed. [1] (.
Jewel case A jewel CD case. A jewel case is a compact disc case that has been used since the compact disc was first released in 1982. It is a three-piece plastic case, measuring 142 by 125 by 10 millimetres (5.59 in × 4.92 in × 0.39 in), a volume of 177.5 cubic centimetres (10.83 cu in), which usually contains a compact disc along with the liner notes and a back card.
A shoe size is an indication of the fitting size of a shoe for a person. There are a number of different shoe-size systems used worldwide. While all shoe sizes use a number to indicate the length of the shoe, they differ in exactly what they measure, what unit of measurement they use, and where the size 0 (or 1) is positioned.
The most common size category. For women of about average height (5 ft 4 in) with an average bust height and an hourglass figure. Dress sizes may be given as girth at the bust in inches (e.g., 36), but even-numbered sizes from 2 to 16 are more common. Categorical sizes range from XS (extra-small) to XL (extra-large).
Lift slab construction (also called the Youtz-Slick Method) is a method of constructing concrete buildings by casting the floor or roof slab on top of the previous slab and then raising (jacking) the slab up with hydraulic jacks. This method of construction allows for a large portion of the work to be completed at ground level, negating the ...
In fluid dynamics, the lift coefficient (C L) is a dimensionless quantity that relates the lift generated by a lifting body to the fluid density around the body, the fluid velocity and an associated reference area. A lifting body is a foil or a complete foil-bearing body such as a fixed-wing aircraft.
Heel lift. Heel lifts, also known as shoe inserts, are commonly used as therapy for leg-length differences leading to knee, hip, and back pain. They attempt to reduce stress on the Achilles' tendon during healing, and for various rehabilitation uses. The intent of a heel lift is not to absorb shock or spread pressure on the foot, but to raise ...
List of battery sizes. 3LR12 (4.5-volt), D, C, AA, AAA, AAAA (1.5-volt), A23 (12-volt), PP3 (9-volt), CR2032 (3-volt), and LR44 (1.5-volt) batteries. This is a list of the sizes, shapes, and general characteristics of some common primary and secondary battery types in household, automotive and light industrial use.
In aerodynamics, the lift-to-drag ratio (or L/D ratio) is the lift generated by an aerodynamic body such as an aerofoil or aircraft, divided by the aerodynamic drag caused by moving through air. It describes the aerodynamic efficiency under given flight conditions.
