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

 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 ...

Calculations of networks fluid flow

Add the pressure drops, set the heights of aspiration, discharge, reservoir pressures ,hydrostatic loads, altitude , temperature, rate of flow , viscosity, density... and thus determine the power of your pump or your turbine (see pump and turbines)

 Calculations pumps
Pump sizes depending on network: know the useful power, consumption, efficiency, cavitation limit in fluids networks..see: Pumps


according to parameters: heights, flow rates, efficiency ... you know the power output of your water column and the power that can return your turbine. see turbines

External flow, Aerodynamics, Hydrodynamics:

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).


New: An export function of your profile, 3d to solidworks

You can set a 4digit profile NACA and automatically generate its coordinates, or
 you use the links to file downloads coordinate profiles available for download, or you use your own measurements.
 You insert the data tables in the editor and your profile emerges.
 You can print your profile
 you can insert the profile in the interface for calculating lift.see: profiles editor
