Determinación del costo diario de una bomba mediante parámetros de diseño para transportar agua desde un río hacia una fábrica.

Abstract

The objective of this work is to determine the daily cost of a pump through design parameters to transport water from a river to a factory. To elaborate the two flow process diagrams, a process simulator called DWSIM was used, where the first diagram was designed according to the problem, and the second diagram was added two standard 90° elbows and a globe valve. To calculate the total friction losses, the Darcy equation was used, to apply this equation parameters such as: fluid velocity, Reynolds number, relative roughness of the pipe and friction factor were determined, with these parameters and the data of the problem were calculated the total friction loss giving a value of 18.14 meters. While, applying the same equation and using the equivalent length method, the friction loss due to accessories was obtained with a value of 20.45m. Regarding the calculation of the power supplied by the pump, two equations were applied; the first is the general energy equation, in which the total friction loss was used, which allowed determining the energy added by the pump, and the second is the equation for the power supplied by the pump. Finally, the daily cost was determined by the value of the power supplied by the pump, operating time and energy cost.
