Q1: given Area = 3.15*10-4m, g=9.81m/s, form your study to calibration of gauge pressure complete the table below showing all calculation then answer the question: Mass(M) (Kg) Force (W) (N) Applied pressure (P) increasing Gauge reading (KN/m) decreasing Average Average error Error (% of full scale) Pg (KN/m) (KN/m) 2.5 3.5 78 77 109 108 a) Explain the difference between Vacuum pressure, absolute pressure and gauge pressure? b) Mention the importance of volumetric hydraulic bench? c) What is the difference between pressure and stress? d) If the volumetric flowrate of water is 51/min, find the mass flowrate in kg/s. Write the solution in details e) What is the material used to made ring of Bourdon tube pressure gauge? and why? f) Where do we use manometers (give a specific answer)? g) If you have a choice to select between u-tube manometer and inclined manometer, which one will you choose? and why?
