Priblem- An inclined manometer is required to measure an air pressure of 3mm of water to an accuracy of +/- 3%.
The inclined arm is 8mm in diameter and the larger arm has a diameter of 24mm. The manometric fluid has density 740 kg/m3 and the scale may be read to +/- 0.5mm. What is the angle required to ensure the desired accuracy may be achieved?
