A particular flow meter allows the volumetric flow rate Q to be calculated from a measured pressure drop Δp. Theory predicts Q ∝ sqrt(Δp), and a calibration provides the following data: Q
(m^3/min): 10, 20, 30, 40 Δp (
Pa): 1,000 , 4,271 , 8,900 , 16,023 What uncertainty in the measurement of Δp is required to yield an uncertainty of 0.25% in Q over the range of flow rates from 10 to 40 m3/min?
