Pressure Drop
Pressure drop across a static mixer ( ΔP static mixer) would be separated into 2 categories, which are laminar mixing and turbulent mixing. A simpler equation has been used to estimate pressure drop across the static mixer, which can be described as a ratio of mixer pressure drop to empty pipe pressure drop ( ΔP empty pipe) for the same fluid flowrate and pipe diameter, namely;
ΔP static mixer = K ΔP empty pipe
Where K is empirical constant depending upon a number of element, Reynolds number, characteristics of fluid, and characteristics of a static mixer.
Lambda static mixers provide efficient mixing, low pressure drop, and easy installation. Mixer elements in pipe are specially designed and securely attached to mixer walls so that the elements cannot be collapsed by pressure flow.
