A pitot-static tube is placed in a subsonic air flow. The static pressure and temperature are 101 kPa and 30°C respectively. The difference between the pitot and static pressure is measured with a manometer and is found to be 250 mm of mercury. Required:
Find the air velocity, assuming the flow to be incompressible and taking compressibility effects into account.

explanation:

earth's surface is mainly heated by the absorption of infrared radiation from the sun.

evaporation occurs because molecules in liquid water are warmed ( usually by the sun) and vibrate quicker, becoming less dense and rise.

condensation occurs because molecules in water vapor are cooled and therefore vibrate more slowly thus becoming more dense and eventually fall to earth.

lines of equal barometric pressure on a weather map are called: isobars : lines of equal temp on a weather map are called: isotherms.​
