the inlet pressure and flow of the liquid the appropriate concentration of the detergent for unifying both phases the capacity of the foaming chamber 6 to generate enough turbulent flow necessary to carry out in a space of not more than 60 cm the mixture of phases without a loss greater of 60 in pressure since the pressure at the discharge head is at least 10 m 1 kg cm 2 taking into account that both are inlet flows and they are newtonian and when the mixture is performed the foam has a non newtonian behavior also the flow has a reynolds 39 number re u2267 2300 derived from the equation flow supply is parallel or crossover as in counter current it causes a much greater loss or can enter to the liquid line and cause damages to the equipment or the system control of air pressures during the supply to prevent that the pressure of any of the fluids obstructs the flow of the other and hinder the proper mixture transportation of foam along pipeline or flexible hoses up to 100 m long and diameters of u00bd inch to 1 inch for direct application to the surfaces of the area to be cleaned fig1 depicts the foaming box 1 having connected a foam outlet hose 3 wherein said hoses can measure up to 100 meter and an inlet hose 4 which carries the detergent solution from the tank container to the foaming chamber with fluidized bed fig2 depicts the interior of the foaming box 1 where the connection of the inlet hose 4 with the.
