- Uconeer Units Conversion Calculator for Engineers
This is a powerful, but easy to use, units conversion tool created specifically for engineers. It includes over 450 units in 48 categories plus you can add your own custom units. Frequently used conversions can be marked as favorites for even faster selection. Special converters are included for viscosity, feet & fractional inches, mass/volume flowrate, steel hardness and Reynolds Number.
- AioFlo Pipe Flow Calculator
Calculate pipe sizes, flowrates and pressure drops for liquids and gases. Includes K-values for a wide selection of fittings and valves, and it has built in databases for pipe size and roughness. Flowrates can be expressed in mass or volumetric terms. It has extemely powerful and flexible units handling capabilities.
- AlcoDens - Ethanol/Water Calculations
Includes 6 utility programs for alcohol distillers. Data is compatible with the OIML model (absolute or "in vacuum" mass) and the TTB model (apparent or "in air" mass). Blending, proofing, dilution and fortification calculations taking into account ethanol-water shrinkage. Hydrometer temperature correction. Conversions between density and concentration for ethanol-water mixtures. Concentrations can be in mass, volume, proof or molar terms. Perform volume corrections and conversion to mass for non-standard temperatures and determine absolute alcohol content. Freezing point calculator for ethanol-water mixtures.
- Packed Column Calculator
Design new or rate existing columns and towers with random packings. Includes database of packings, but you can use your own packing factors as well. Includes Eckert and Robbins correlations. Generates operating diagrams to clearly show range of operation. Works in SI, Metric and US Customary units.
- WASP - Water and Steam Properties
Physical Properties of Ice, Water and Steam in a wide range of units. It contains data for 15 fixed and 17 variable properties from -100 to 800 deg C and up to 1000 bar.
- Project Risk Analysis
Calculate the risk of project over-expenditure, and the contingency required to reduce the risk to any desired level. The required contingency is determined using the proven statistical method known as Monte Carlo Simulation. No statistical knowledge is required. Includes detailed online Help with step-by-step tutorials and examples.
- Turbine Steam-Consumption Calculator
This program is completely free - simply download it and use it. It will calculate the steam consumption for a turbine of known power and efficiency. The required input data are the inlet steam pressure and temperature, and the exhaust pressure. The program will determine the specific and actual steam consumption, and the outlet steam enthalpy, entropy, temperature and quality. The program is very easy to use because all the required steam properties are built in. A wide variety of units of measure are included.
Background Information Articles
We have written a few articles giving background details on some of the methods used in our software. These may be of general interest, beyond just being background to the software.
- How to use Monte Carlo simulation to calculate the project cost contingency required
This article describes how the cost estimate for a project should be built up by estimating the potential cost variation for each item. The variations and risks for each of the items are then combined using Monte Carlo simulation to give the overall risk and required contingency for the project as a whole.
- Why Project Costs are "Expected" to Overrun
An internet search for "reasons for project cost overruns" will give many articles discussing these reasons. But the most important reason for project cost overruns, and sadly the one that is virtually never mentioned, is that there is a fundamental flaw in the way most cost estimates are put together. The explanation for this built-in error depends on some elementary statistics, which are easily understood and which can easily be applied to eliminate the errors.
- Hydrometer temperature correction
Hydrometers are useful and relatively cheap instruments, but have the disadvantage of requiring the liquid to be at a specific temperature for a measurement to be made. The method described here allows the readings taken for ethanol-water mixtures at any temperature to be corrected to the hydrometer's calibration temperature. This method is incorporated in the hydrometer temperature correction module built into AlcoDens.
- Alcohol dilution blending and fortification calculations
This article compares 3 methods for calculating alcohol dilution ratios. The advantages and shortcomings of each method are discussed and examples are given. The 3 methods covered are the AlcoDens Blending Calculator, The TTB Table No.6 Method and the Pearson's Square Method.
- Railroad track method for manual unit conversions
Although our Uconeer engineering units converter is the best way to get rapid, reliable and accurate unit conversions there will be times when you need to convert units by hand. It's easy and logical to do by hand using the railroad track method. This methoid is also known as the factor label method.
- Pressure drop calculation methods for pipe fittings
Piping engineers often need to convert between equivalent lengths (Le/D) and resistance coefficients (K-values) when calculating pressure drops or flow rates through pipe fittings and valves. Here is a discussion on the relative merits of these methods and how to convert between them.
- Tables of Equivalent Lengths for pipe fittings in plastic and steel pipe
The article above describes how to use the Equivalent Length Method, and this article gives the necessary data to apply the method for a wide variety of pipe fittings and valves for both plastic (PVC, CPVC, HDPE, GRP/FRP) and steel (commercial and spiral welded) pipe.
- Project Risk Analysis manual and tutorials
The complete manual for the Project Risk Analysis program is included in the Help system for the latest version (i.e. v3.0) of the program. However, for those users who like to work with printed manuals the manual for the previous version is available in PDF format online. Although the instructions for how to use the program are a bit out of date, it also includes tutorials which describe the use of statistical distributions in capital cost estimating. There is information on the application of Monte Carlo Simulation to the determination of the contigencies required to reduce and control the risk of capital cost over-runs of project budgets. All this information is in the latest Help system, so it is only worth downloading if you want something easily printable.
