A Pitot tube device is utilized for the measurement of_________________?
Show answer Hide answer
Answer: C. velocity
Explanation
A Pitot tube operates on the principle of converting kinetic energy into static pressure. By measuring the stagnation pressure minus the static pressure, it determines fluid speed. Therefore, this specialized instrument is utilized specifically for the measurement of fluid velocity. Invented by Henri Pitot, the device features an open tube pointing directly into fluid flow. Bernoulli equation principles govern the mathematical calculation of velocity from pressure heads. Manometers or differential pressure transducers are attached to read the resulting pressure difference.
Aviation engineers mount Pitot tubes on aircraft exterior surfaces to measure airspeed safely. Mechanical engineers use them in ductwork and pipe networks to test industrial fluid flow rates. Accurate velocity measurement is vital for aerodynamic testing and ventilation system balancing. Option A is incorrect because pressure is measured by standard gauges rather than Pitot tubes. Option B and D are wrong because flow rate and discharge require cross-sectional area calculations. Option E is incorrect because viscometers measure fluid viscosity instead of velocity.
