This lesson will allow you to experience the part, assembly, and drawing modes (Fig. 1.1) of Pro/ENGINEER Wildfire 3.0 by creating two simple parts (Figs. 1.2 and 1.5), assembling them, and creating drawings A bare minimum of explanation is provided here. This lesson will quickly get you up and running on Wildfire 3.0 Download: http://www.almohandes.org/upload/529wildfire-tips.pdf [...]
IC engines: chemical energy to work via internal energy – unfortunately not all chemical energy converted to useful work. Material balances: pollutants production per unit fuel. Heat of reaction: pollutant production per unit energy released. 1stLaw (energy balance): energy split between work, heat etc. 2nd Law of Thermodynamics: nothing can be 100% efficient. Thermodynamic efficiency: [...]
Current GPS sensing technology enables estimation of road grade and, consequently simple treatment of parameter estimation from a static mass balance. An on-line recursive parameter estimation scheme based on this idea has been developed and demonstrated experimentally with a passenger vehicle. Both methods for estimating road grade from GPS produced a rapidly converging mass estimate [...]
The Engineering of Pt/Carbon Catalyst Preparation For application on Proton Exchange Fuel Cell Membrane This paper will deal with the strong electrostatic adsorption (SEA) method used for catalyst preparation of Platinum on carbon supports for use in proton exchange fuel cell membranes (PEFCM). The main objective is to optimize dispersion and loading of Pt on [...]
TAROL units (Tapered Roller Bearings) are double row tapered roller bearings that are supplied with factory-set clearance, greased and sealed. The TAROL units are thus supplied ready-to-fit and are pressed onto the shaft journal by means of a hydraulic unit. http://www.almohandes.org/upload/489tpi156_de_en.rar
Air pressure (psig or bars) at motor location. 2. Pipe size of air supply system to assure adequate volume (cfm or m3/min) so as to minimize line loss (air pressure drop during motor operation). 3. Plant air system pressure may vary during the day due to use by other equipment; therefore, base the selection of [...]
This paper deals with the energy audit analysis of a dry type rotary kiln system working in a cement plant in Turkey. The kiln has a capacity of 600 ton-clinker per day. It was found that about 40% of the total input energy was being lost through hot flue gas (19.15%),cooler stack (5.61%) and kiln [...]
In a recent consulting assignment we realized that there was some lack of understanding of the whole system of project cost control, how it is setup and applied. So we decided to write up a description of how it works. Project cost control is not that difficult to follow in theor http://www.almohandes.org/upload/552cost_control.rar
Cutting costs is the simplest way to improve your bottom line. Introducing a cost control system can bring immediate savings and ensure that you remain competitive in the longer term. http://www.almohandes.org/upload/711st2cost.rar
