1. Derive equation for Pitot-Static probe or Pitot-Darcy probe for velocity measurement.
2. Determine velocity of oil inside a pipe flow and measured by Pitot-Static probe if pressure P1-P2 =
50 kPa and S.G. oil is 0.9.
3. Determine velocity of gas inside a pipe flow if water manometer connected to Pitot-Static probe show 2.5 cm height. Take density of water and air 1000 kg/m3 and 1.25 kg/m3.
4. Determine velocity of water inside a pipe flow if mercury manometer connected to Pitot-Static probe show 10 cm height. Take density of mercury and water 13600 kg/m3 and 1000 kg/m3.
5. Describe 5 advantage and disadvantage of orifice and venturi flowmeter.
6. Derive equation for obstruction flowmeters which is connected to a manometer if d is obstruction opening at point 2, D is diameter of pipe at point 2, ρB is the density of moving fluid, ρM is the density of manometer fluid, h is height of manometer fluid and β is ratio of d/D. fluid d
