The Three Laws of Motion The basis of all solutions to mechanics problems are the Newton’s laws of motion in one form or the other. The laws are: First law: A body does not change its state of motion unless … Continued
Degree of saturation or percentage humidity: We have already discussed that the degree of saturation is the ratio of actual mass of water vapour in a unit mass of dry air to the mass of water vapour in the same … Continued
Psychrometric Relation: Specific humidity, humidity ratio or moisture content: It is the mass of water vapour present in 1 kg of dry air (in the air-vapour mixture) and is generally expressed in g/kg of dry air. It may also be … Continued
Dalton’s Law of Partial Pressures: It states, "The total pressure exerted by the mixture of air and water vapour is equal to the sum of the pressures, which each constituent would exert, if it occupied the same space by itself". … Continued
