Utility Software

CoolPack	CoolPack is a collection of simulation programs related to refrigeration. It consists of "Refrigeration Utilities", "EESCoolTools", and a transient element called "Dynamic". Created by Univ. of Denmark
WSProps	WSProps is an excellent free program to calculate the properties of water and steam for temperature ranging from 273.16°K to 1273° and pressures up to 10000 bar. WSProps can be used in routine thermodynamic calculations as well as steam turbine design and simulation. Created by Open Source
Flange Design	ASME Code, Section VIII, Div. 1, Appendix \"Y\" Flange Design Program. Flat Faced Flanges With Metal-To-Metal Contact Outside the Bolt Circle. Programmed in a template form, for class 1 and category 1, Appendix \"Y\" flange assembly. The program runs in MathCad 2000 or later. All the flange factors (i.e. F, V, FL, VL, f, T, U, Y & Z) are calculated internally. Created by William Rowell Screen Shot
Engineering Power Tools	A program that does calculations for all those commonly stumbled upon mechanical and electrical components, material properties, structural data, bending stresses and all.It is a shareware and can be used for a period of 30 days after which it is required to be registered. The "Save" function is crippled. @1MB Created by Engineering Power Tools
Energy Conversion	A demo for Energy converting systems, also for Power and Propulsion systems. However the demo version is crippled to allow only the following options to be functional. Under Thermodynamic properties only Enthalpy and pressure are functional From the Power cycles only the Brayton cycle is active. Power cycle components, only combustion by Oil/Coal. From compressible flow only Normal Shock and Thrust. @3.5MB Created by EngWare
Archon	20 demo mechanical engineering programs . Can be used for rountine calculations of bending/buckling loads, thread loads, plates etc. They are Windows based and have a lot of useful features active, a few utilities though may be crippled. Created by Archon Engineering
Convert	An exhaustive Units Conversion freeware for 22 different technical quantities such as power, pressure, speed, torque, force, area, energy, distance etc. Created by Josh Madison
FLUIDTOOLS	Tools for imcompressible liquid and compressible gas flow. The demo is restricted to solve for a max diameter of 1.5inch. Created by Phelps Software
Turbine Steam-Consumption Calculator	This free program will calculate the steam consumption for a turbine of known power and efficiency. The required 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. The program is very easy to use because all the required steam properties are built in. Created by Katmar Software
Uconeer	This free units conversion program is designed specifically for engineers. It includes a wide range of technical categories required by engineers, but it excludes the archaic and esoteric units that clutter the menus of the other conversion programs. In addition to the standard categories Uconeer includes categories like Diffusivity, Enthalpy, Entropy, Fouling Factor, Heat Capacity, Heat Transfer Coefficient, Moment of Inertia, Stress, Surface Tension, Thermal Conductivity, Torque and Viscosity. There are a total of 370 units in 42 categories. Created by Katmar Software
AxCom	Utility for shaft design. After specifying the shaft dimensions, material properties, & loads the strength, stress, deflection, safety factor is display graphically. Screen Shot Created by DimTech
CadMechanic	Lots of AutoCAD productivity enhancing little utilties, and some for pipe design. Created by Hamilton Design Group
FluidProp	Program calculates thermodynamic and transport properties for a large variety of fluids and fluid mixtures. Created by Delft University of Technology
Frame2D & others	Distributed or nodal dead and live loads can be specified. Load combination is used according to Eurocode 1, with user defined load combination coefficients. The program performs computation of internal forces and diagrams for displacements, bending moments, shear and axial forces. In the dynamic analysis the eigenfrequencies and the mode shapes are computed. Graphical output for the diagrams and mode shapesis displayed. For educational purposes FREE Light version Created by Runet

Piping

Within industry, piping is a system of pipes used to convey fluids and gases, from one location to another. The engineering discipline of piping design studies the best and most efficient manner of transporting fluid to where it is needed.

Industrial process piping (and accompanying in-line components) can be manufactured from wood, glass, steel, aluminum, plastic and concrete. The in-line components, known as fittings, valves, and other devices, typically sense and control the pressure, flow rate and temperature of the transmitted fluid, and usually are included when one discusses the concept of piping design. Piping systems are documented in Piping and Instrumentation Diagrams. If necessary, pipes can be cleaned by the tube cleaning process.

Plumbing is a piping system that most people are familiar with, as it constitutes the form of fluid transportation that is used to provide potable water and fuels to their homes and business. Plumbing pipes also remove waste in the form of sewage, and allow venting of sewage gases to the outdoors. Fire sprinkler systems also use piping, and may transport potable or nonpotable water, or other fire-suppression fluids.

Piping also has many other industrial applications, which are crucial for moving raw and semi-processed fluids for refining into more useful products. Some of the more exotic materials of construction are titanium, chrome-moly and various other steel alloys.

Pipe stress analysis

Process piping and power piping are typically checked by pipe stress engineers to verify that the routing, nozzle loads, hangers, and supports are properly placed and selected such that allowable pipe stress is not exceeded under the appropriate ASME code.^[3]^[4] This checking is usually done with the assistance of a finite element pipe stress analysis program such as Caesar II, CAEPIPE and AUTOPIPE.
