n: C6H6 colourless, volatile, flammable toxic liquid aromatic hydrocarbon used as a solvent and as a motor fuel.

an aromatic (cyclic or ring structure) compound, present in very minor quantities in many crude oils.

v: to make a gift of personal property by means of a will. Compare devise. Bernoullis theorem n: a mathematical expression of the conservation of energy in streamline flow;the theorem states that the sum of the ratio of the pressure to the mass density, the product of the gravitational constant and the vertical height. and the square of the velocity divided by 2 are constant.

n: one of the extremely small particles, sometimes called rays, emitted from the nucleus of a radioactive substance such as radium or uranium as it disintegrates. Beta particles have a negative charge.

an electron emitted with high energy and velocity from a decaying nucleus.

a specialized viscosimeter.

valve designed for blocking the fluid in upstream and downstream directions.

n: the radius of the rounded portion of a vessels shell that connects the bottom to the sides.

a rheological model used to describe flow in some fluids. Bingham fluids have a linear shear stress, shear-rate behavior after an initial shear-stress boundary has been crossed. Plastic viscosity or PV is the slope of the line. Yield Point is the threshol

n: the total mass of living organisms per unit volume per unit of time.

n: 1. the emptying or depressurising of material in a vessel.2.the material thus discarded.
