Presentation Transcript

  1. Drill: Write down these questions and have 2 answers per questions. Be as specific with your answers as possible. IOTPOLYENGINEERING I1-07 • Questions that we deal with • Why do we measure? • What do we measure? • How do we measure? • When do we measure? • Where do we measure? • Who measures?

  2. IOTPOLYENGINEERING I1-07 METROLOGY is the science of measurement, based on the Greek word ‘metron’. METROLOGY should not be confused with meteorology.

  3. INTRODUCTION TO METROLOGY IOTPOLYENGINEERING I1-07

  4. IOTPOLYENGINEERING I1-07 Measuring instruments • Ruler • Thermometer • Barometer • Clock • Scale • Voltmeter • GPS • Hydrometer • Viscometer • Graduated Cylinder • Radar Gun • Speedometer • Tachometer • Accelerometer • Spectrometer • Protractor • Compass • Sphygmomanometer

  5. Base Units IOTPOLYENGINEERING I1-07 • 7 FUNDAMENTAL SI UNITS: • LENGTH - meter • MASS - kilogram • TIME - second • ELECTRIC CURRENT - ampere • THERMODYNAMIC TEMPERATURE - Kelvin • AMOUNT OF MATTER - mole • LUMINOUS INTENSITY - candela

  6. IOTPOLYENGINEERING I1-07 LENGTH English System 1 foot =12 inches 1 yard = 3 feet 1 mile = 5280 feet Metric System 1 m = 100 cm 1 m = 1000 mm 1 km = 1000 m 1 in = 2.54 cm

  7. IOTPOLYENGINEERING I1-07 MASS English System 1 lb = 16 ounces 1 ton = 2000 lbs Metric System 1 kg = 1000 g 1 g = 1000 mg 1 lb = 2.2 kg

  8. IOTPOLYENGINEERING I1-07 Time 1 minute = 60 seconds 1 hour = 60 minutes 1 day = 24 hours 1 year = 365 days

  9. Metric System Prefixes IOTPOLYENGINEERING I1-07

  10. Metric System IOTPOLYENGINEERING I1-07 • WHAT IS THE DEFINITION OF … • MICROSECOND • TERABYTE • CENTIMETER • KILOJOULE 10-6 Seconds 1012 Bytes 10-2 Meters 103 Joules

  11. Derived Units IOTPOLYENGINEERING I1-07 A car travels 30 miles in 30 minutes. What is the speed of the car in miles/hr? New unit of measure of speed based on Length/Time

  12. Derived Units IOTPOLYENGINEERING I1-07 What is the volume of a 3ft x 2ft x 6ft block of wood? Derived measurement of volume based on ft3
