    Benefits of CAD

    , , , , , , , , , ,

    CAD has the following advantage over traditional method of design- (i) Computer aided design (CAD) is faster and more accurate results than conventional methods. (ii) Developing the design of component and associated drafting is a very easy task with CAD. (iii) Manipulation of various dimensions,attributes and distance of drawing elements,is very easy.This make CAD the most useful designing…

    Portable room cooler

    , , , , ,

    A portable room cooler is an electrical appliance used for cooling and ventilating a room of medium size.It is more effective than ordinary electric fans because it performs the added function of blowing out air which circulates through filter pads that contain water.This further cools the air which is then blown outwards. The working action…
