A U-tube manometer and an inclined-tube manometer are used to measure pressure ranging from 200P a to 400P a at 20oC. The resolution of the U-tube manometer is 1mm with a zero error of 0.5mm. The resolution of the incluned-tube manometer is 1mm, zero error of 0.5mm, with an angle of inclination of 30 ± 0.5 o . Calculate the uncertainty in pressure measurements of these two instruments and comment on the results.
