Flow Measurement - Pitot Static Tubes Bernoulli's Equation etc.?

  1. Jan 24, 2012 #1
    A Pitot-static tube connected to water manometer is used to measure the velocity of air. If the deflection between the two arms of the manometer is 12.4cm, determine the air velocity when the density of air is 1.25kgm-3 and the density of the water in the manometer is 1000kg/m3.

    I am not really sure where to start as i dont have the pressures...do i?

    Thanks

    You have the pressure differential since you have the difference in height of the two sides of the manometer.

    Thank you for your reply, so what equation do i use from here? My pressure differential is 12.4 cm?

    Thanks

    You already said it. Bernoulli.
