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 up = 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.
