turbulent flow

แปลว่าการไหลแบบปั่นป่วน : ดู flow, turbulent

Statically equivalent:

แปลว่า(english) Two force systems are statically equivalent when their resultants are equal. Physically, this means that the force systems tend to impart the same motion when applied to an object; note that the distribution of resulting internal forces in the object may be different.

Brass

แปลว่า(english) An alloy that is 70% copper,30% zinc. One of the most widely used of the copper-zinc alloys; malleable and ductile; excellent cold-working but poor hot-working and machining properties; excellent for soft-soldering; good for silver alloy brazing or oxyacetylene welding, but fair for resistance or carbon-arc welding. Used for drawn cartridges, tubes, eyelets machine items and snap fasteners.

velocity, critical

แปลว่าความเร็ววิกฤต : ความเร็วของกระแสน้ำเมื่อการไหลเริ่มเปลี่ยนจากการไหลแบบราบเรียบ(laminar flow) ไปเป็นการไหลแบบปั่นป่วน (turbulent flow) หรือ คือความเร็วของกระแสน้ำซึ่งมี Froude number เท่ากับ 1

Couple:

แปลว่า(english) A system of forces composed of two equal forces of opposite direction, offset by a distance. A couple is statically equivalent to a moment whose magnitude equals the magnitude of the force times the offset distance.

Equivalent

แปลว่า(Environmental Engineering) The mass of the compound which will produce one mole of available reacting substance. Thus, for an acid, this would be the mass of acid which will produce one mole of H+, for a base, one mole of OH-.

Stress resultant:

แปลว่า(english) A system of forces which is statically equivalent to a stress distribution over an area.

Covalent bond

แปลว่า(Environmental Engineering) A bond in which electrons are shared approximately equally by two atoms.

Equivalent Joint Load

แปลว่าแรงกระทำเทียบเท่าที่จุดต่อ

Softening

แปลว่า(Environmental Engineering) The removal of divalent cations by precipitation or ion exchange.

Body-Centered

แปลว่า(english) Having the equivalent lattice points at the corners of the unit cell, and at its center; sometimes called centered, or space-centered.

Resultant:

แปลว่า(english) The resultant of a system of forces is a single force or moment whose magnitude, direction, and location make it statically equivalent to the system of forces.
