equipment.GravityChamber module

class equipment.GravityChamber(**kwargs)

Bases: Separador_SolidGas

Class to define a gravity chamber for separation of solid from gaseous stream

Parameters:

entrada: Corriente instance to define the input stream to equipment metodo: Integer to define the calculate type

0 - Rating of a equipment with known geometry and input stream 1 - Design of a equipment to meet a required efficiency

modelo: Integer to define the method to calculate

0 - Plug Flow model without vertical mixing 1 - Perfect mix

W, H, L: dimensión of equipment (width, height, length) rendimientoAdmisible: Required efficiency of equipment, mandatory if

chosen method of calculate is design

velocidadAdmisible: Maximum speed of gas in chamber, default 1 m/s deltaP: Pressure loss
