1. What is the advantage of using variable area rotameter? 2. Identify the plane of reading of following Rotameter float 3. wnat is the power requirement of venturimeter and orificemeter? 4. A venturimeter having a throat diameter of 38.9mm is installed in a line having an inside diameter of 102.3mm. It meters water having a density 999kg/m3, the measured pressured drop is 156.kPa. The venturi coefficient is 0.98 . Calculate flow rate. 5. An orifice meter with flange taps is to be installed in a 100mm line to measure the flow of water. The maximum flow rate is expected to be 50m3/hr at 15C. a) If maximum manometer reading is to be 1.25m. What will be the diameter of the orifice? b) What will be the power to operate the meter at full load? 6. State Bond Law. Define work index. 7.
