ABSTRACT:
The present invention relates to a method for designing handling systems such as pipeline systems for fluid products such as emulsions and dispersions which deteriorate at elevated temperature and pressure. The method of the present invention comprises the steps of providing a pipeline having a fluid inlet point and a fluid discharge point and at least one pump for transporting the fluid from the fluid inlet point to the fluid discharge point, selecting one of a maximum pressure drop to be encountered by the fluid as it travels from the fluid inlet point to the fluid discharge point and a maximum volume of fluid to be handled by the system, and operating the system in accordance with the following equation: ##EQU1## where B is the maximum allowable shear rate from a first fluid inlet point to a second fluid discharge point, D is the diameter of the pipeline, and Q is the volume of fluid to be transported between the fluid inlet point and the fluid discharge point.
