1. A precision bourdon tube is stated to have an absolute accuracy of ±0.1 percent of full-scale reading of 1 MPa. What is the percent accuracy (uncertainty) when the gage is employed for a differential pressure of 40 kPa in air at 3 atm and 20?C?
2. An assembly of two reservoirs and a small-diameter tube inclined at 30? with the horizontal operates as a micro manometer using water and an oil of specific gravity 0.85 as the two fluids. Calculate the sensitivity of the device expressed in mm/Pa.
