2. Bathtub refinishing - Wikipedia

   en.wikipedia.org/wiki/Bathtub_refinishing

   Bathtub refinishing (also known as bathtub reglazing, bathtub resurfacing, or bathtub re-enameling) is a process of restoring the surface of a bathtub to improve its appearance and durability. It involves applying a new coating or finish on the existing bathtub surface, which can be made of materials such as porcelain , fiberglass , acrylic ...

   Water delivery requirements [ edit ] Requirements for the quantity of water discharge are specified by an applicable model code such as NFPA 13, NFPA 15, EN 12845, BS 9251, [ 4 ] NFPA 750 CP 52, ASIB, and AS2118.1.

4. Bathtub curve - Wikipedia

   en.wikipedia.org/wiki/Bathtub_curve

   The bathtub curve is a particular shape of a failure rate graph. This graph is used in reliability engineering and deterioration modeling. The 'bathtub' refers to the shape of a line that curves up at both ends, similar in shape to a bathtub. The bathtub curve has 3 regions: The first region has a decreasing failure rate due to early failures.

5. Hydraulic clearance - Wikipedia

   en.wikipedia.org/wiki/Hydraulic_clearance

   Leakage in narrow clearance, spool valve. Hydraulic clearance. Flow in narrow clearances are of vital importance in hydraulic system component design. The flow in a narrow circular clearance of a spool valve can be calculated according to the formula below if the height is negligible compared to the width of the clearance, such as most of the clearances in hydraulic pumps, hydraulic motors ...

6. Engineering fit - Wikipedia

   en.wikipedia.org/wiki/Engineering_fit

   Engineering fits are generally used as part of geometric dimensioning and tolerancing when a part or assembly is designed. In engineering terms, the "fit" is the clearance between two mating parts, and the size of this clearance determines whether the parts can, at one end of the spectrum, move or rotate independently from each other or, at the other end, are temporarily or permanently joined.

7. Bathtub - Wikipedia

   en.wikipedia.org/wiki/Bathtub

   A bathtub, also known simply as a bath or tub, is a container for holding water in which a person or another animal may bathe. Most modern bathtubs are made of thermoformed acrylic, porcelain-enameled steel or cast iron, or fiberglass-reinforced polyester. A bathtub is placed in a bathroom, either as a stand-alone fixture or in conjunction with ...

   The clearance for overhead signs is 5.7 metres (18 ft 8 in) and the clearance for the soffit or underside of overpasses is 10 metres (32 ft 10 in). [ 6 ] In South Africa and the southern region of Africa, the minimum vertical clearance of modern bridges is 5 metres (16 ft 5 in), although the legal height limit of road vehicles is still at 4.3 ...
