LMTD stands for Log Mean Temperature Difference. It is used in heat exchanger design to calculate the average temperature difference between hot and cold fluids.

• LMTD is used to determine the overall heat transfer coefficient in a heat exchanger.

• It is calculated using the formula: LMTD = (ΔT1 - ΔT2) / ln(ΔT1 / ΔT2)

• LMTD helps in determining the required heat transfer area for a given heat exchanger design.

• It is important...read more

Distillation is a process of separating components of a liquid mixture based on their boiling points.

• Distillation involves heating a liquid mixture to create vapor, then cooling the vapor to collect the separated components.

• Types of distillation include simple distillation, fractional distillation, and steam distillation.

• Simple distillation is used to separate components with significantly different boiling points, whi...read more
