Pumps are devices used to move fluids through a system. There are various types of pumps such as centrifugal, positive displacement, and reciprocating pumps.

• Types of pumps include centrifugal, positive displacement, and reciprocating pumps

• API standards for pumps include API 610 for centrifugal pumps and API 674 for reciprocating pumps

• Pump design considerations include flow rate, pressure, material compatibility, and efficiency

Storage tank design involves following API standards and various types of storage tanks.

• API standards such as API 650 for welded steel tanks and API 620 for large, field-erected tanks

• Types of storage tanks include atmospheric storage tanks, pressure storage tanks, and refrigerated storage tanks

• Design considerations include material selection, tank size, pressure requirements, and safety features

Dimensionless numbers are used in engineering to simplify equations and compare different systems.

• Dimensionless numbers help in scaling and comparing physical phenomena without the need for specific units.

• Examples include Reynolds number in fluid mechanics, Mach number in aerodynamics, and Peclet number in heat transfer.

• They provide insight into the dominant forces or mechanisms in a system.

• Dimensionless numbers are used to predict flow patterns, heat transfer rates, and othe...read more

Line sizing procedure involves determining the appropriate diameter of pipes for a given flow rate and pressure drop.

• Calculate the required flow rate and pressure drop for the system

• Use fluid properties and pipe material to determine the appropriate pipe size

• Consider factors such as velocity, friction loss, and future expansion

• Ensure the selected pipe size meets safety and regulatory requirements

• Common methods include using pipe sizing charts, software programs, or hand calcu...read more

Heat exchanger design involves selecting the appropriate type, size, and materials to efficiently transfer heat between two fluids.

• Consider the type of heat exchanger needed (e.g. shell and tube, plate heat exchanger)

• Calculate the required heat transfer area based on heat load and temperature difference

• Select materials compatible with the fluids and operating conditions

• Optimize flow rates to maximize heat transfer efficiency
