The most dominant male birds in the area is the first to break the night-time silence with their call, followed by the second most dominant. Cockerels (like those abve) call in the morning according to the social hierarchy of the flock, with the most dominant male crowing first, according to a study.
A low-precision gravimetric titration can achieve 10,000.the same. reproducibility as a titration with a 50 mL volumetric buret. It requires less reagent quantities, it is faster and less. complicated titration for the students and the teacher, and the equipment. is far less expensive.
Cv = Valve flow coefficient, dimensionless; Q = Volumetric flow rate, gpm; q = Volumetric flow rate, scfh; Gf = Liquid specific gravity at upstream conditions [ratio of density of liquid at flowing temperature to density of water at 15.6Â°C (60Â°F)], dimensionless Gg = Gas specific gravity (ratio of flowing gas to density of air with both at standard conditions, which is equal to the ratio of the molecular weight of gas to the molecular weight of air), dimensionless
