, Dos and Don’ts in the Lab
DOs: -
1. Come in time wearing appropriate dress neatly. Maintain discipline and punctuality.
2. Come prepared for the experiment you are going to perform by understanding the relevant
background material in your textbook, or in library references.
3. Come to laboratory with a plan in mind with proper preparation.
4. Students should carry observation book, pen, pencil, calculator and any other items that are
necessary in the lab.
5. Submit the completed record of previous experiments conducted in every class.
6. Correct specifications of the equipment have to be mentioned in the diagram.
7. Do the connections neatly and firmly tightened with proper value of the component.
8. After completing the connections, Students should request the teacher to verify the
connections before switching ON the motor.
9. Student should be aware of operating equipment. In case of doubt, obtain clarification from
the teacher. Set the correct range and function
10. Note that the equipment once switched ON need not be switched OFF till the end of the
experiment; frequent switching ON and OFF will reduce the life of
11. Students should be at their concerned experiment table, unnecessary movement is restricted.
12. The values recorded during the experiment must be shown to the Faculty for verification.
13. Students must ensure that all switches are in the OFF position and all the connections are
removed before leaving the lab.
14. Arrange the equipments properly and make sure that all the items are returned
before leaving the lab premises. Keep all knobs of sources at their minimum position.
15. Keep all your valuable items with personal care; lab personnel are not responsible for
your items.
16. MAINTAIN SILENCE!
DON’Ts: -
1. Don’t bring eatables. Mobile phones are prohibited in laboratories.
2. Don’t keep unwanted materials on the worktable.
3. Don’t make or remove the connections with the power ON.
4. Don’t leave the lab without the permission of the Faculty In-Charge.

, EXPERIMENT 1
DETERMINATION OF THE COEFFICIENT OF DISCHARGE
OF GIVEN
V- NOTCH
Aim:
To determine the coefficient of discharge of V-notch
Apparatus used:
Supply tank, Hydraulic Bench, Hook and Point gauge, Stopwatch, Collecting tank, Scale
and V-notch
Diagram:
V- notch:
A V-notch is used to meter flow in an open channel. By applying Bernoulli equation
(conservation of energy equation) to a simplified flow model of a V-notch, we can develop
the following relationship for discharge through V-notch:
Where,
Qth = Theoretical Discharge
g = Acceleration due to gravity
θ = the enclosed angle of the V
H = Head above bottom of
