Bernoulli’s theorem states that for an inviscid flow of a non conduction fluid , an increase in the speed of the fluid occurs simultaneously with a decrease in pressure in the fluid’s potential energy
Gas permeability is the degree to which a substance resists permeation of a gas under pressure
Coke is a solid fuel made by heating coal in the absence of air, so that the volatile components are driven off
Thermo-electricity in physics, is electricity generated by the application of heat to the junction of two dissimilar materials. If the two wires of different materials are joined at their ends and one is maintained at a higher temperature than the other, a voltage difference will arise and an electric current will exist between the hot and the cold junctions.
