New: sizing flues: A calculation tool diameters, height of the chimneys and the flue based on the power of the heat generator and minimum speeds of flue pipes according to their sulfur content, requested by heating installers..

New: editor and search for pump operating points: Graphical analysis was increased by an editor pumps used to test the network in comparison with the curves of pumps that you entered in the pump editor .. The pumps are created with the input of 6 points height curves, depending on the flow. A photo and information features, price, supplier...,Can be entered by copying and pasting from a pump builder's website, and stored in a database available for research operating points. The coupling in series and in parallel, can be tested at the same time.

Authority valves, Cv and Kv conversion coeff loss: A small well tool useful to test the authority of a valve according to the pressure loss of the portion that must be controlled.

New Graphical network analysis in a range of flow rates: The graphs show the proportion of losses by network elements, energy consumption and the cost of losses. Whether an element is improperly sized, this will appear with evidence in operating cost or loss of pressure. This allows to visualize the consequences of choice of material in terms of operating costs and create simulations of different networks in order to find the best compromise.
 Sizing ducts imposed by the flow This interface allows you to select a list of pipes within trade stocks, or from a series of DN, And automatically search for the best duct, according to the criteria of linear head loss, Installation cost, sedimentation, usually applied in the hydraulic or ventilation professions. A compromise is proposed around 15 mm / m (linear head loss), but the interesting data who is highlighted, is the evolution of the pressure drop as a function of diameter. The choice of the user can be, depending on the damping strategy and expected operating. sizing duct

 Approximately 120 fluids are already set in density, viscosity, temperature.
 you can create, save, edit, new fluids according to your own parameters. see: fluid Editor
Head loss calculation:
 Major head losses calculation after choosing the size of your hydraulic line, flow and roughness ( the most common 10 materials pipes, are already integrated, but you can enter your own roughness) , the major head losses (or linear) is given in sevearl units: fluid M.colonne / Pascal / bars
 Minor head losses calculation:(43 bases accessories and fittings configurable, allow you to simply study the minor pressure losses through a network of elements , valves, elbow, cones, outputs tanks, fittings.... See: Minor head losses calculation
 head loss Inventory , the duckwork installation or hydraulic: Losses calculated charges are stored into an editor to view the various calculations and add them, or turn them off: see: head loss Inventory

All these results can be recorded in a result sheet, showing the calculation parameters and results ...

Calculation of friction of a surface in a fluid stream

Enter the dimensions of the surface, roughness, fluid's relative velocity and select fluide. The friction forces are given to you as well as distances transitions flow regimes and boundary layer thicknesses. This detailed study, indicates the proportion of ship resistance to advance, due to frictional forces on a surface. See friction surface


drag calculations, of an object immersed in a fluid stream(friction force + Turbulence)

You choose a basic geometric shape (30 forms configurable basics), you set its dimensions, fluid, velocity and get the drag (resistance to forward)

Select a vehicle and speed, you will have the power it must provide to overcome the forces of resistance to progress, due to the fluid displaced.

Calculating sedimentation velocity:("tools")
 You enter your particle diameter and fluid parameters, and you have the speed of sedimentation, according to the laws of Stokes See: sedimentation
 You can use the Midship (front surface) and Cd (aerodynamic coefficient) pré paramétrés, preconfigured, or enter the desired values for a calculation of drag. See Aerodynamic/hydrodynamic drag


Calculations of lift and drag of an aerodynamic or hydrodynamic profile (Lift force + friction force + Turbulence)

You choose an airfoil or wing (12 profiles are integrated with their polar), you select or set a fluid, enter the speed, the incidence and size of the wing or sail or daggerboard. The results give you the lift and drag of your wing , the Reynolds number, the Cd (aerodynamic drag coefficient) and CL (aerodynamic lift coefficient) to provide power to overcome drag (takeoff).
