Frequently Asked Questions

Can your spreadsheets be delivered via email?

Yes. After you've placed your order you'll receive instructions to download the file from the website. However, if you can't download but need an email attachment instead, forward me a copy of your purchase receipt and I'll reply with the file attached.

Will your software run in Open Office?

No. Our software requires Excel with Visual Basic for Applications (VBA).

Will your software run on a Mac?

Maybe. Our software requires Excel with Visual Basic for Applications (VBA). Some versions of Excel running on a Mac include VBA, but others do not. A Mac running Windows as a parallel operating system, with Excel for Windows installed, is compatible with our spreadsheet products.

Do you have “demo” versions of your products?

No. Our software is very inexpensive, and it is open source. Rather than create crippled or highly protection versions that could be used for demo purposes which would add to our costs and result in higher prices, we offer a 100% money-back, no questions, return policy.

Will you help me if I have questions when solving problems using your spreadsheets?

Yes! Customers often send questions by email. You can expect prompt, courteous, and thorough responses to your queries.

We are looking to calculate the impact of pressure & temp rating on the external area of a pressure vessel. We need to know the required wall thickness of our tanks to make them safely and to have them conform to ASME code. Could your tankjkt program do these calculations?

Sorry. TANKJKT is intended for performing heat transfer calculations. You need software that is specifically designed for ASME tank design

Does TANKJKT account for heat gains/losses to the environment, heat of reaction/dissolution, and heat input from agitators?

No. TANKJKT calculates heat flux from the jacket and internal coil (if any) to or from the content of the vessel. Energy gains or losses to the environment must be calculated separately and are not part of the TANKJKT spreadsheet. Contact us if you need help with these calculations.

What chemicals are included in the TANKJKT database?

A complete list of the chemicals included in the TANKJKT database are listed here. You can easily add your own chemicals to the database. When you provide properties at multiple temperatures, the program creates an expression that returns the property (density, viscosity, thermal conductivity, specific heat, and vapor pressure) at the temperature needed for the calculation.

We love your Tank Volume spreadsheet, but would like to add a strapping table, formatted to match our existing documents. Can this be done?

Yes! Our spreadsheets are open source so you can customize them as you like. We can do the customization for you; contact us for a proposal.

What does “tangent-to-tangent” wall height mean?

Tanks have a straight side and usually a dished head attached to the ends. The “tangent-to-tangent” dimension is the distance from where the curve begins on the dished heads. The heads include a short straight section (often about 1 inch, 25 mm) which is included in the tangent-to-tangent dimension.

Will PIPESIZE handle gases (hydrogen and carbon dioxide) at rates down to 0.06kg/hr?

Yes. Although PIPESIZE has a built-in database of pipes and tubing that only goes down to about 1/8" diameter, you can build your own table of tubing sizes that can be anything you need. The pressure drop equations are equally valid for very small and very large flow rates and pipe/tube sizes.

What chemicals are included in the PIPESIZE database?

A complete list of the chemicals included in the PIPESIZE database are listed here. You can easily add your own chemicals to the database, or you can just enter the properties (density and viscosity) when solving a problem.
