Frequently Asked Questions

Q. What is the difference between the Branch and DesigNet versions?
A. Both versions provide both liquid and gas analysis. The Branch version solves problems for single lines with all the components in series. The DesigNet version provides complete flow analysis for networks.

Q. What data is included?
A. Data includes a comprehensive water database (subcooled, superheated, and saturated data), common gases (air, oxygen, hydrogen, helium, ammonia, nitrogen, others), liquid chemicals (ammonia, mercury, sodium hydroxide, others), freons, brines, alcohols, and hydrocarbons (oils, fuels, natural gas, others). Additional data is available (see data library section).

Hardware data includes standard pipe dimensions, valves (20 types), orifices (sharp-edge, beveled, rounded, and thick), and common fittings (tees, elbows, bends, reducers, enlargers). Additional data is available (see data library section).

Q. Are the libraries included in any of the versions?
A. No. The libraries are optional packages of data which expand the capabilities of the software. The professional version and the DesigNet version allow similar data files to be created. The libraries simplify this process by providing ready-made data files.

Q. What are the system requirements?
A. DF Solutions runs under all versions of Windows 98 and newer. The software requires from 15 to 20 MB of disk storage (depending on version), and 256 MB of memory. A VGA (1024X768) or better display is required.

Q. What is the difference between the single-user version and the LAN version?
A. The single-user version can be used by one user at a time. It can be installed on a single machine or on a single network server.

The LAN version is designed to be installed to and run from a single network server. Up to the licensed number of users can run the software simultaneously. No software is installed on the client machines. The software performs its own usage metering.

Q. What computer network types are supported?
A. DF Solutions is not designed for any specific network and has been used successfully on a wide variety of computer networks.

Q. Does Design Flow Solutions include the data from TP410?
A. Design Flow Solutions includes standard data typically used in the power and petrochemical industries. The data includes specifications for valves, pipes, etc and data on various fluids. All the information is from numerous public available sources. In addition, ABZ provides data libraries to complement the standard data included in the program.

Q. Does Design Flow Solutions incorporate the methods and techniques for calculating fluid flow that are part of TP 410?
A.The basic “methods” of TP 410 are the Darcy formula and Bernoulli’s equation. These are basic engineering principles and are not unique to TP 410. Design Flow Solutions uses these same principles.
