Our Pick |
 |
|
 |
is a molecular visualization software adapted from the program RasMol. I had been looking for a replacement for the formerly free WebLab Viewer program, and this is an outstanding candidate. |

(US units only) This program contains several functions commonly used by mechanical engineers. These functions include a pipe database, flange dimensions, pressure/temperature ratings, hardness conversions, wire gage dimensions, minimum pipe wall calculator, units conversion, stress intensity factors (SIFs) and a pressure drop calculator. |

This program calculates the pressure loss of fluids flowing under pressure in circular pipes. The program can calculate flow in either compressible mode (for gases) or incompressible flow. It allows a choice of units: gpm, pph, scfm, or acfm. Any single-phase liquid or gas can be accepted. The properties of water, steam and air are built in. |

This program uses the iterative Hardy-Cross algorithm to determine the flow and pressure loss in each leg of a series-parallel pipe network |

This program provides Psychrometric properties of air given two properties as input values at a known altitude (or atmospheric pressure). The properties are determined using the ideal gas law for the behavior of air. Once the properties are determined, the point is indicated on the Psychrometric chart. Process lines can be connected between any two know points, this will provide the user with the differences in moving from one point to the next. Additionally, this program will allow the user to perform some basic HVAC calculations that depend on psychrometrics. |

PHEdesign 1.0 program for simulations of the plate heat exchanger. By setting our controlled variables and material properties, the optimum plate dimensions and materials can be selected by the computer program. These are included rate of heat transfer, the size of plate heat exchanger, and chevron angle (beta) between 25 to 65 degrees under single pass condition. Also this program is capable of calculating the pressure drop in plate, from which the energy and material can be saved by decreasing the pressure drop (decreasing horsepower per unit area) and increasing chevron angle |

This program calculates the amount of steam that can be generated by a fired or unfired waste heat boiler (Heat Recovery Steam Generator). The steam and condensate properties are built in. The program first calculates a design mode and then an "off-performance mode" for changed conditions. |

Heat Exchanger Performance is a powerful, user friendly, program for the analysis of two types of Heat Exchangers: Shell & Multi-Tube Exchangers, and Double Pipe Exchangers. In either case, the tubes are of the bare-tube type. The program will analyze the performance of a known heat exchanger: Given the flows and inlet temperatures of the Tube-side fluid and the Shell-side fluid, the program will predict the exit temperatures of both fluids and the total heat exchanged. |
