- Buyer's Guide
SFA Soft recently launched two new smartphone apps with more than 30 technical calculators for pumping machinery professionals and those who design and install electrical systems.
Electric Calcs and Pump Calcs, which are available for both Apple and Android devices, can be downloaded for free through the App Store and Google Play.
The Electric Calcs app calculators can determine the voltage drop in copper and aluminum wiring circuits, calculate real (true) power in three-phase transformers, and analyze transformer ratio data.
The Pump Calcs app calculators can estimate the required brake horsepower for a given centrifugal pump application, determine efficiency of a motor-driven centrifugal pump, and calculate the average fluid velocity in a pipe when the flow rate is known.
Both free versions allow access to the basic technical calculators. There is a one-time cost of 99 cents for Electric Calcs and $1.99 for Pump Calcs to remove ads and enable the use of the more advanced calculators.
SFA Soft, which has been developing and managing database-driven technical websites since 2004, also plans to launch mobile-friendly websites for the electrical and pump calculations by the end of the year.
