CE25C07:

Fluid Mechanics and Machinery Laboratory

Course Objective:

To provide hands on experience in calibration of flow meters, performance characteristics of pumps and turbines.

List of Experiments:

1. Flow Measurement Devices

Calibration of rotameter and flow measurement using venturimeter/orifice meter/notches.

2. Bernoulli’s Theorem - Verification of Bernoulli’s equation.

3. Losses in Pipes - Determination of friction factor and minor losses.

4. Pumps - Performance characteristics of centrifugal and reciprocating pump.

5. Turbines -Performance characteristics of Pelton and Francis turbine.

6. Metacentric Height - Determination of metacentric height of floating bodies.

Tasks: (Perform any 2 tasks)

Task 1: Compare discharge values obtained from different devices and analyze errors.

Task 2: Evaluate major and minor losses in the system and Compare experimental

results with theoretical/Moody chart values.

Task 3: Plot performance curves and determine the specific speed of a centrifugal pump

Task 4: Plot characteristic curves (H–Q, η–Q) and determine efficiency of a reciprocating pump.

Task 5: Assess stability conditions and compare with theoretical values.
