1 EXPERIMENTAL METHODS IN THERMAL ENGINEERING P M V Subbarao Professor Mechanical Engineering Department Man is the measure of All things.. Measurement is the cornerstone of our life..

2 “When you can measure what you are speaking about, and express it in numbers, you know something about it; but when you cannot measure it in numbers, your knowledge is of a meagre and unsatisfactory kind... ”. -- Lord Kelvin No amount of experimentation can ever prove me right; a single experiment can prove me wrong. --Albert Einstein

3 Theory of Measurements Philosophy of Measurements

4 Why do We Need to Measure?

5 Why do We Need Measurement? If we are living in a cave, we need not measure to a precise standard. We might be having fire, stick and stone tools in our cave. There, starts a measurement system. Like when you grunt and say how many beast you killed for dinner, 1, 2 or 3.....measurements. When gathering wood for a fire you would ask for so much wood.....measurement. To live in our physical world we need to understand it (The Knowledge).

6 What is Present? Measurement is KEY to the knowledge and interaction. A Science & Technology of a measured understanding. Science is about doing and making, not just thinking. It is crucially an experimental activity, directed to measurement. In Engineering & Technology; Responsible people seek the most measured way to understand their situation. Any inquiry will get ignited as Engineering only when its practitioners become serious about the practice of measurement. Measurement functions not simply to furnish a test of some theory, but rather as a direct argument to a specific theoretical conclusion. The more the measured understanding is in practice, the more harmonizing its engagement of the evidence will be.
