TURBNPRO Software Awards:

Hydro Info Systems is proud to have donated copies of TURBNPRO as awards to winners of the Hydro Power Contests held at the bi-annual Hydro Vision and Water Power conferences. Congratulations to all the winners.

TURBNPRO Version 3 includes the following additional features:

- In addition to Francis and Axial/propeller type turbines, TURBNPRO Version 3 includes Pelton turbines. All major turbine types are therefore covered by the software.

- In response to User demand, all data entry is in SI units (meters, m³/s, etc.). In addition, all data results are also in SI units. Printed reports continue to show results in both SI and US Customary units.

- An option is included in the Configure Turbine screen which allows Users to enter efficiency modifiers to further customize the turbine solution performance. Two styles of modifiers are available. One is a simple multiplier which reduces or increases the turbine efficiency while the other is a modifier which reduces or increases the turbine efficiency as a function of the square of the discharge.

- The dimension values developed by the program are displayed directly on to the graphic screens. These screens are the generic graphics of the turbine cross-section, waterpassage, arrangement, etc. which are shown as part of the Solution Summary.

History of TURBNPRO :

September, 2000: TURBNPRO Version 3.04 is released and available to all users of Version 3.0x. Version 3.04 includes minor corrections to cavitation characteristics of Axial/Propeller units. This new version creates more realistic axial unit sizes/speeds particularly when used in higher head applications.

August, 2000: Two copies of TURBNPRO were awarded to winners of the Hydro Power Contest held at the Hydro Vision 2000 conference in Charlotte, North Carolina.

March, 2000: TURBNPRO Version 3.03 is released and available to all users of Version 3.0x. Version 3.03 includes minor corrections to the labeling on the print-outs of the Annual Energy Report and the Solution Summary Report.

January, 2000: TURBNPRO Version 3.02 is released with minor programming refinements.

October, 1999: TURBNPRO Version 3.01 is released and issued to users of Version 3.0. Version 3.01 includes a correction to the Axial/Propeller Crossplot programming which had previously developed misleading efficiency data due to rounding of the relatively low net head values being used.

July, 1999: Two copies of TURBNPRO Version 3.0 are awarded as second place prizes in the student division of the 1999 Hydro Power Contest held during the Waterpower ‘99 conference in Las Vegas, Nevada. Award is mentioned in October, 1999 issue of HYDRO REVIEW magazine.

April, 1999: TURBNPRO Version 3.0 for Windows 95/98 is completed and released. Version 3.0 covers Pelton as well as Francis and Axial/Propeller type hydraulic turbines and all data entry is in SI (Metric) units.

1998: A news release regarding TURBNPRO Version 2.0 is published in Volume 5, Issue Two of The International Journal on Hydropower & Dams magazine.

December, 1997: A news release regarding TURBNPRO Version 2.0 is published in International Water Power & Dam Construction magazine.

March, 1997: TURBNPRO Version 2.0 for Windows 3.1 is completed and released. Version 2.0 covers only Francis and Axial/Propeller type hydraulic turbines and all data entry is in US Customary units.

October, 1995: TURBNPRO Version 1.0 for DOS is completed.
