In a PIV system, the displacement of the fluid at a particular location is measured to be 4.1 pixels in the CCD camera, with a magnification factor of 10 (1 cm on the image corresponds to 10 cm in the flow). The camera has a 2/3 size CCD sensor (16 by 24 mm) and is a 6-megapixel camera (2000 by 3000). The time between exposures is 10 ms. What is the measured velocity? If the uncertainty in the PIV software is ±0.1 pixel, what is the uncertainty in the measured velocity?
