EXPERIMENT NO-1 AIM- To determine the frequency of A. C. mains by using an electric vibrator. APPARATUS- Electric vibrator‚ table lamp‚ pulley‚ weight box‚ fishing cord‚ a. c. source. THEORY- when a cord of mass per unit length m is connected to the vibrating rod of the vibrator and stretched with a tension T‚ the cord vibrators in segments. If the length of the cord is then adjusted until the nodes are clearly marked‚ the frequency of the stretched string is the same as of the vibrating rod which

Compounds of manganese range in oxidation number between theses two extremes. This experiment involves the preparation of a Mn (III) complex of actylacetone (also named 2‚4-pentanedione) which is a useful starting material for the preparation of other Mn (III) compounds. Manganese (III) complexes are relatively stable and can be prepared

Design of Experiments (DOE) Tutorial Design of Experiments (DOE) techniques enables designers to determine simultaneously the individual and interactive effects of many factors that could affect the output results in any design. DOE also provides a full insight of interaction between design elements; therefore‚ it helps turn any standard design into a robust one. Simply put‚ DOE helps to pin point the sensitive parts and sensitive areas in designs that cause problems in Yield. Designers are then
