A U-tube manometer indicates a pressure drop of 10 inches water across an air filter.The air is at 26 degrees celsius and a gauge pressure of 60 lb/in^2.
a.) What is the pressure drop in lb/in^2 and in atm?
b.) What percentage of error is introduced if the density of the air in the manometer leads is neglected?
