Unformatted text preview: mercury ( = 13,600 kg/m 3 ) as the manometer fluid. The difference in column height between the two legs of the manometer is h = 1.20 cm. To do : Calculate the air speed at the location of the Pitot-static probe. Solution : Hg Manometer h air V V j Example Given : Doppler radar is used to measure the speed of a baseball as sketched (not to scale). The radar frequency is 12,000 MHz. To do : Calculate the maximum angle that will yield less than 1% error in measuring the speed of the baseball. Solution : V Pitchers mound Doppler radar...
