Tahoe Design PumpBase v2.0c
PumpBase finds the best pumps for your fluid conveyance application. You can refine your selection by specifying up to 40 selection criteria. PumpBase's database contains thousands of curves from dozens of participating pump manufacturers. Detailed reports are created that can be submitted to pump manufacturers and sales representative for further application verification and price quotes.
Features:
- Complete pump curve database access and editing.
- Communicates with HYDROFLO for system curve development.
- Quick affinity law conversions for speed and trim.
- Extensive and editable liquid property database.
- Automatic viscosity corrections to pump curves.
- Efficiency and NPSHR curves are plotted on pump graphics.
- Both English and SI (metric) units.
- User Project files save all selection information.
- Technical Bulletins/Dimensional Schematics available.
- Liquid temperature rise calculations.
Operation: View all pumps by default. As you add restrictions, the database is filtered for those criteria. Optionally specify operating point data TDH (total dynamic head) and operating flow to select pumps whose operating envelopes include the operating point. Specify NPSHA (Net Positive Suction Head Available) to restrict selection to pumps whose NPSH required is adequate for operation. Specify (or select) liquid property data to obtain pumps that can provide the required flow and TDH. Enter just the pumped liquid properties and view pump curves with viscosity corrections applied. Manual correction factors can be specified and applied to stocks, slurries and other liquids. Specify additional selection criteria such as specific manufacturer, curve key, series/model, speed, 60/50 Hz, max sphere size, pump orientation (horizontal, vertical, in-line, side-suction, end-suction), application type (fire, well, process, sludge/slurry, dewatering, sewage, wastewater, HVAC), features (portable, submersible, split-case, solids handling, non AC powered, self-priming, high temperature, high corrosive, ANSI, ISO 2858). |

GeoStru Slope 2013 v8.18.1.1001
Slope carries out the analysis of soil or rock slope stability both in static and seismic states utilizing the limit equilibrium methods of Fellenius, Bishop, Janbu, Bell, Sarma, Spencer, Morgenstern & Price and Discrete elements method (DEM) for circular and non circular surfaces by which it is possible to ascertain slippages in the slope, examine a gradual failure, and employ various models of force-deformation relationship. Reinforcements with piles, gravity and/or reinforced concrete bracing walls, nettings, geofabrics, anchors, and terracing may be specified. Distributed and point loads may be defined. |

GeoStru LoadCap v2012.15.0.559
LoadCap id design for the computation of limit load in loose soils or rock, according Terzaghi, Meyerhof, Hansen, Vesic, Brinch-Hansen, Richards etc. Al, the computation of bearing capacity factors (according to the instructions for the geotechnical design in seismic areas - Italian Association of Geotechnical Engineering).
Settlements: Elastic (Timoshenko and Goodier), Oedometric, Schmertmann, Burland & Burbidge, liquefaction usig the method of Seed and Idris (1971). The settlements can be calculated at any point either inside or outside the foundation. Limit load in seismic conditions: SHIKHIEV & JAKOVLEV, RICHARDS, NTC 2008 Circolare applicativa.
Diagrams: Limit load as a function of the foundation base, of the depth of the bearing surface, of the acting loads. Unlimited number of layers. Display of pressure bulbs and failure wedges. Supported computation standards: Eurocode 7/8, British Codes BS8004, Norme tecniche costruzioni (NTC 2008), NTC - Circolare 2 Febbraio 2009, n. 617, C.S.L.LPP. |

GeoStru Dynamic Probing v2012.18.0.423 + Static Probing v2012.12.1.339
Dynamic Probing.This software performs Dynamic Penetrometry, that is the reading, recording, interpretation, storage and the management of any type of penetrometer including new or custom equipment and of in borehole SPT readings. Dynamic Probing provides functions for the archiving of readings by site and for automatic calculation of the real energy transmitted, including correction for warp and the correlation coefficient with SPT (standard reference tests for geomechanic calculations and geotechnic correlations). Processing of data is instantaneous, deriving the values of Ndp&Rd and immediately generating a graphic display. In addition, the software proposes discrete layer boundaries and enables bitmaps or colors to be assigned for lithologic coding. In geotechnic calculation for coherent and incoherent terrains, several correlations are available for diverse lithologic types, which provide a more precise ‘geotechnic calibration’ for the specific trials zone.
Static Probing. This program processes and archives penetrometric equipment readings for static penetrometers such as CPT (Cone penetration test), CPTE (Cone penetration test electric) and CPTU (Cone penetration test Piezocone). Step intervals - even centimetric- are user selected. The most authoritative lithographic and stratigraphic interpretation methods are used, both the more traditional (Begemann e Schmertmann) and the more recent (Robertson, Douglas-Olsen, Koester etc.) with standard or "normalized" values for qc & fs. Stratigraphic interpretation may be performed either automatically or at user selection based on site experience. Electronic data gathering unit outputs can be input directly to the program. The program provides the facility to calculate directly bearing capacity parameters for surface or deep foundations. |
