Fluid Mechanics And Machinery

Positive Displacement Positive Displacement Notes
  positive-displacement (PD) pumps displace a known quantity of liquid with each revolution of the pumping elements. This is done by trapping liquid between the pumping elements and a stationary casing. Pumping element designs include gears, lobes, rotary pistons, vanes, and screws.

Fluid Mechanics Fluid Mechanics Notes
  Fluid Mechanicsis that section of applied mechanics, concerned with the statics and dynamics of liquids and gases.A knowledge of fluid mechanics is essential for the chemical engineer, because the majority of chemical processing operations are conducted either partially or totally in the fluid phase.

Postive Displacement Pumps Postive Displacement Pumps Notes
  A Positive Displacement Pump has an expanding cavity on the suction side of the pump and a decreasing cavity on the discharge side. Liquid is allowed to flow into the pump as the cavity on the suction side expands and the liquid is forced out of the discharge as the cavity collapses.

Darcy-Weisbach Formula Darcy-Weisbach Formula Notes
  The flow of liquid through a pipe is resisted by viscous shear stresses within the liquid and the turbulence that occurs along the internal walls of the pipe, created by the roughness of the pipe material.
