A Pitot-static probe is used to measure the speed of an aircraft flying at 6000 m. If the differential pressure reading is 3600 N/m2, determine the speed of the aircraft in m/s. The density of air at an altitude of 6000 m is 0.66 kg/m3. The speed of the aircraft is m/s.

Asteam is contained in a rigid tank with a volume of 1 m3. initially, the pressure and temperature are 7 bar and 500 oc, respectively. the temperature drops due to cooling process. determine: (1) the temperature at which condensation begins in °c, (2) the fraction of the total mass that has condensed when the pressure decreased to 0.5 bar. (3) the volume in m3 occupied by saturated liquid at the final state?
