In aircraft design, the pressure coefficient p c is usually measured during wind tunnel testing of an aircraft component to predict structural loads, as well as lift and drag forces. let 2 0.5 p p p c v − = , where v is the airspeed of the test at pressure p and using a fluid of density . the pressure difference p p − is measured where p is located at a point on the surface of the test component. estimate the uncertainty in p c under the following conditions: 2 = − = p p p 1000 n/m , 2 up = 15 n/m ; 3 = 1.20 kg/m , 3 u = 0.01 kg/m ; v 50.0 m/s = , 0.21 m/s v u = . assume 95% confidence in stated values.
