- - - - family can be updated as schedule in the sheet
        
        click on project browser in the sheet family
        
        go in the sheet tab
        
        you will get the list of availble schedule pasted on sheet
        
        single click on one of the schedule withpout opening it
        
        check its properties now, these will be editable.
      - New revision number can be added by going to view
        
        Clicking on revision tab
      - Adding/changing a revision number on sheet can be done from sheet properties
        
        Click on revision
  - - - start the heading with main number of which series will follow.
        
        then after writing the key number and key value again use tab and write the main series number.
        
        this will allow to form sub category of the series number you are writting in the end.

  - - - these are schematic drawings generated to understand the loop of mechanical system and then implimented on site with actual construction
        
        revit has the ability to read the P&ID drawings and suggest rectifications if the loop is not drawn accordingly.
        
        We need to map the drawing symbols first before Revit can read the drawings.

        creating a pleanum level is very important
        
        other wise Revit (volume bounding) consider the air above ceiling as out door air, which is supposed to be extremely hot or cold.

        unit of pressure
        
        It is defined as the pressure exerted by a column of water of 1 inch in height at defined conditions. At a temperature of 4 °C (39.2 °F) pure water has its highest density (1000 kg/m3). At that temperature and assuming the standard acceleration of gravity, 1 inAq is approximately 249.082 pascals.[2]
        
        STP
        
        standard temperature and pressure
        
        STP or standard temperature and pressure, standard conditions for measurement of the properties of matter. The standard temperature is the freezing point of pure water, 0°C or 273.15°K. The standard pressure is the pressure exerted by a column of mercury (symbol Hg) 760 mm high, often designated 760 mm Hg.
        
        density vs Viscosit
        
        Viscosity describes a liquid's resistance to flow—compare molasses and water, for example—and is measured in pascal-seconds. Density is a measure of the mass of a substance per unit volume and is measured in grams per milliliter.
        
        ESP
        
        ESP is the static pressure "external to the HVAC Equipment" needed to overcome only the duct and fittings friction losses. External Static Pressure is the resistance to airflow (friction) caused by the air moving through duct and it parts
        
        Static pressure is one of the most important factors in HVAC design. Simply put, static pressure refers to the resistance to airflow in a heating and cooling system's components and duct work. The push of the air must be greater than the resistance to the flow or no air will circulate through the ducts.
