The number of plates in a distillation column can be found using the McCabe-Thiele method.

• The McCabe-Thiele method involves constructing a graph of the distillation process and determining the number of theoretical plates required for separation.

• The method takes into account the vapor-liquid equilibrium data and the reflux ratio of the column.

• The number of plates can also be estimated using empirical correlations or si...read more

Net Positive Suction Head (NPSH) is the difference between the absolute pressure at the suction of the pump and the vapor pressure of the liquid.

• NPSH is a critical parameter in pump design and operation.

• It determines whether the pump will cavitate or not.

• Cavitation can cause damage to the pump and reduce its efficiency.

• NPSH is affected by factors such as fluid properties, pump speed, and suction piping design.

• NPSH can ...read more
