equipment.Neumatic module

class equipment.Neumatic(**kwargs)

Bases: equipment

Class to define the pneumatic conveying equipment

Parameters:

entrada : Corriente instance to define the input stream to equipment D : Pipe diameter orientation : Geometric orientation of pipe

0 - Horizontal 1 - Vertical

saltationMethod to calculate saltation velocity of gas:

0 - Kizk (1973) 1 - Matsumoto (1977) 2 - Matsumoto (1975) 3 - Matsumoto (1974) 4 - Ochi (1991)

fsMethod to calculate solid friction factor

0 - Stemerding (1962) 1 - Reddy-Pei (1969) 2 - Swaaij-Buurman-Breugel (1970) 3 - Capes-Nakamura (1973) 4 - Konno-Saito (1969) 5 - Yang (1978)

eD : Pipe roughness, optional for Ochi saltation velocity method L : Pipe length K : Equivalent length of pipe fittings
