hvac ducting principles and fundamentals pdhonlinelow velocity ductwork design is very important for energy efficiency in air distribution systems. low velocity design will lead to larger duct sizes, but it may be worth since, doubling of duct diameter will reduce friction loss by a factor of 32 times and will be less noisy. the low velocity systems
electrochemical noise electrochemical noise (ecn) is the generic term given to fluctuations of current and potential.when associated with corrosion, it is the result of stochastic pulses of current generated by sudden film rupture, crack propagation, discrete events involving metal dissolution and hydrogen discharge with gas bubble formation and detachment.the technique of measuring electrochemical noise uses no
bulk electrolysis bulk electrolysis is also known as potentiostatic coulometry or controlled potential coulometry. the experiment is a form of coulometry which generally employs a three electrode system controlled by a potentiostat.in the experiment the working electrode is held at a constant potential and current is monitored over time ().in a properly run experiment an analyte is quantitatively converted from
