Design size

It is the energy in the liquid rec]uired to overcome the friction los.ses from the suction nozzle to the eye of the impeller without causing vaporization. It is a characteristic of the pump and is indicated on the pump s curve. It varies by design, size, and the operating conditions. It is determined by a lift test, producing a negative pressure in inches of mercury and converted into feet of required NPSH. 

Whenever two-phase flow is encountered in facility piping it is usually in flowlines and interfield transfer lines. Some designers size liquid lines downstream of control valves as two-phase lines. The amount of gas involved in these lines is low and thus the lines are often sized as singlephase liquid lines. Oversizing two-phase lines can lead to increased slugging and thus as small a diameter as possible should be used consistent with pressure drop available and velocity constraints discussed in Volume 1. 

The design, size and siting of the boiler feed tank or hotwell must be compatible with the boiler duty capacity and system temperatures. They should be installed giving sufficient space for access to controls, valves and manways. 

All boiler plants, irrespective of design, size, pressure, or location, need as a minimum to be supplied with RW of a basic good quality that is consistently clean and clear throughout the seasons. Further treatment may be necessary.

As with all process equipment, the design size of an evaporator system is dependent upon volumetric flow, specifically the rinsewater flow rate required and the volume of process solution dragout. When operated properly, a commercial evaporator can attain a 99% material recovery rate. 

Electrodialysis is compatible with most plating baths, and the design size of a unit is dependent upon the rinsewater flow rate and concentration.22... 

The primary application of the VSP is to obtain data necessary to calculate the vent design (size and relief setting) for emergency venting of nonvolatile and reactive runaway systems. The calculated vent design is to limit the maximum pressures at the point of emergency venting to acceptable levels. A secondary application is to provide thermal stability data for reactive systems. 

When specified, proposed connection designs shall be submitted to the pnrchaser for approval before fabrication. The drawing shall show weld designs, size, materials, and preweld and postweld heat treatments. 

For GMP regulations in the United States issues related to equipment are covered in Subpart D [7], which consists of regulations 211.63, 211.65, 211.67, 211.68, and 211.72. Contents of Subpart D are presented in Table 19. Regulation 211.63 states the requirements for the production equipment covering design, size, and location. Regulation 211.65 states the requirements for the construction of equipment cover-... 

Design. Sizing has been based on laboratory experiments and field experience. No equations based on first principles have been advanced. Design is based on a flux rate of up to 40 gpm/sq it of foam cross-sectional area. 

Design. Sizing of dissolved gas flotation units is based on a hydraulic loading in gpm/sq ft of cross sectional area of the cell. Sport reported using a value of 2.0 gpnvsq ft for full pressurization systems, and 4.0 gpm/sq ft for recycle systems.1... 

It not only synthesizes the HEN structure, but also designs (sizes) the individual exchangers. 

The proper design, sizing, selection, manufacturing, assembly, testing and maintenance for such AMSEI SRVs are all critical to obtain optimum protection.
