Create dynamic Pump/Valve models in VB or VC++

Here's a challenging one. I need some one to create dynamic models of process devices for the following items: Valve - varying types, liquid and Gas Pump - varying types, liquid and gas Vessel - sealed and open Flow Spliter (Splits one flow stream to Multiple resultant streams with flow/temp/pressure) Flow Mix (joins multiple flow streams to one resultant flow/temp/pressure) Each model should have the following resultant properties: temp out, pressure out, flow out The models will be have all relevant engineering info entered by setting model properties (ie CV, Valve Type, etc...). The models can use standard Engineering equations or dynamic time based models if coder thoroughly understands the use. The coder will have to determine the correct equations to do this. The coder will bid a combined price The coder will make a basic gui (textbox or whatever_ to demonstrate the calculations in response to varying process values All flows should be in mass units ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Installation package that will install the software (in ready-to-run condition) on the platform(s) specified in this bid request. 3) Complete ownership and distribution copyrights to all work purchased. ## Platform win 2000/xp
