Consider a glider flying at 400 meters altitude, when suddenly all its static ports become blocked by volcanic ash. The pressure at 400 meters altitude is 96,610 Pascals. The glider then descends to near sea-level and flies at a true airspeed of 25 m/sec. What is the airspeed indicated by the pitot-tube driven airspeed indicator in m/s?

4r-134a enters the condenser of a residential heat pump at 800 kpa and 50°c at a rate of 0.022 kg/s and leaves at 750 kpa subcooled by 3°c. the refrigerant enters the compressor at 200 kpa superheated by 4°c determine (a) the isentropic efficiency of the compressor, (b) the rate of heat supplied to the heated room, and (c) the cop of the heat pump. also, determine (d) the cop and rate of heat supplied to the heated room if this heat pump operated on the ideal vapor-compression cycle between the pressure limits of 200 and 800 kpa.
