engineering recuitment GATE IN Test Series 2023-24 Mock Test Sensors and Industrial Instrumentation Measurement of Flow Differential Pressure
A pitot tube is used in a pipe to measure the flow velocity by differential pressure measurement using u-tube manometer. At maximum flow rate the differential pressure is 100 kPa. If the manometer has 1% uncertainty, then the flow velocity including uncertainty measured by the pitot tube is – (Take P = 100 kg/m3).
