# REGULATION SYSTEMS

## MAIN FEATURES

• Selection of an unlimited number of systems and valves for each analysis
• Description of each system through data provided from surveys (e.g. gross head, pipe length, pipe diameter, pipe roughness, range of operation, etc.)
• Description of each valve through data supplied from manufacturers (e.g. diameter, coefficient of contraction, coefficient of velocity, range of operation, etc.)
• Computation of characteristic surfaces (i.e. head and head loss versus valve opening and discharge for all system and valve combinations) according to hydraulic laws
• Identification of working conditions (i.e. balance between gross head and head losses due to friction in pipes and valves)
• Comparison of analytical results with available field data (e.g. head and head losses versus valve opening and discharge, etc.)
• Visualisation of results
• Suitable for designing and testing

## OPTIONS FOR IO OPERATIONS

• Microsoft Excel Spreadsheet Files (xlsx)

## OPTIONS FOR GRAPHICS

• Standard Image Formats (jpeg, tiff)
• Portable Document Format (pdf)

## TEST CASES

Figure 1, Figure 2, Figure 3 and Figure 4 illustrate the behaviour of the very same hydraulic system working with different regulation valves. Blue solid meshes represent the gross head of the system while red solid meshes show the friction losses due to both pipe and valve. Interception of the meshes denote actual working conditions.

Figure 1. Head (Z-Axis) versus valve opening (X-Axis) and discharge (Y-Axis). C_C = 0.20 and C_V = 1.00.

Figure 2. Head (Z-Axis) versus valve opening (X-Axis) and discharge (Y-Axis). C_C = 0.40 and C_V = 1.00.

Figure 3. Head (Z-Axis) versus valve opening (X-Axis) and discharge (Y-Axis). C_C = 0.60 and C_V = 1.00.

Figure 4. Head (Z-Axis) versus valve opening (X-Axis) and discharge (Y-Axis). C_C = 0.80 and C_V = 1.00.
