Among the benzene-based direct dyes that can be used according to the present disclosure, mention may be made, in a non-limiting manner, of the following compounds: 1,4-diamino-2-nitrobenzene; 1-amino-2-nitro-4-β-hydroxyethylaminobenzene; ...
The range of Reynold's numbers within which the surface-active agents have a maximum friction-reducing effect is among others dependent on the concentration, the range increasing with the concentration. By choosing the right concentration of surface-active agents and suitable flow rates in tubings ...
