The air velocity in the duct of a heating system is to be measured by a Pitot-static probe inserted into the duct parallel to the flow. The differential height between the water columns connected to the two outlets of the probe is 0.126 m. Take the density of water to be 1000 kg/m3. The gas constant of air is R = 0.287 kPa-m3/kg-K. The air temperature and pressure in the duct are 352 K and 98 kPa, respectively.
