Abstract: Pitot-tube is widely used to measure the air velocity. The coefficient must be calibrated to correct the measurement result. LDA (laser Doppler anemometer) can be applied to calibrate Pitot-tube to acquire the coefficient . During the process, the calibration result can be influenced by the flow round the probe of Pitot-tube and air velocity distribution deviation in long axis. The experiments are conducted to evaluate or correct this influence. In ideal condition, the velocity measured by Pitottube can be calculated by:
