RATIONALE:

In Diploma level engineering education skill development plays a vital role. These

can be achieved by experience in handling various equipments. This is accomplished by

doing engineering related experiments in practical classes.

GUIDELINES:

All the experiments should be completed and given for the end term practical

examination.

� The external examiners are requested to ensure that a single experimental question

should not be given to more than eight students while admitted a batch of 30 students

during Autonomous Examinations.
