1. VENTURIMETER A flow meter is a device that measures the rate of flow or quantity of a moving fluid in an open or closed conduit. The most widely used flow metering principle involves placing a fixed area flow restriction of some type in the pipe or duct carrying the fluid. This flow restriction causes a pressure drop that varies with the flow rate. Thus, measurement of the pressure drop by means of a suitable differential-pressure pick up allows flow rate measurement. The important flow meters are A venturi meter is a device which is used to measure the rate of flow or discharge in a pipe. It works on principle of measurement of pressure drop in the direction of flow that facilitates in the determination of the discharge. The pressure drop is created by the reduction of flow area in the flow direction. It consists of three parts: convergent cone, throat and divergent cone. The convergent cone is of shorter length so as to accelerate the fluid with lesser energy loss and the dive...

Working with Layers Working  with  Layers  is  analogous  to  drawing  manually  using  Layers  of  see-through  media.   Parts  or portions  -  these might be functional portions, such as Construction Lines,  of one complete drawing are drawn on different 'media' that, imposed on top of one another, form the entire drawing. Layers are useful in  separating  entities,  such  as  parts  or  sub-assemblies,  or  structural  components,  such  as  pipe  sizes  or building materials. They also serve to separate elements such as Construction Lines, Centerlines, Outlines, and Dimensions, or items  that are to be placed in a group, such as foliage in an architectural drawing. When you use Layers, you have a clearer construction of the drawing and better control over the drawing. Layer 0: The Default Layer The default Laye...
