On a mollier diagram show all the stagnation and static points required to represent the complete flow process in a diffuser. air enters a diffuser with an average velocity of 375 m/s at a stagnation pressure and temperature of 360 kpa and 470 k respectively and leaves at a stagnation pressure of 300 kpa with an average velocity of 120 m/s and a static pressure of 280 kpa. determine (i) the static pressure and mach number of the air at inlet (ii) the diffuser efficiency, (iii) the mach number at exit and the overall entropy increase.

An insulated tank truck containing 50,000 pounds of double-distilled, deionized water at 30 °c is pumped into a closed, refrigerated storage tank maintained at 5 °c in a facility located on top of mount mitchell, north carolina (elevation 6,684 feet & average july temperature of 84 °f). a)-determine the volume of the storage tank required to hold the purified water. b)- determine the initial and final pressure differences that must be overcome by a liquid pump assuming the storage tank initially contains air at 5 °c. assume the air is slowly bled out of the storage tank during the water transfer c.) during a routine operation today, the tank is slightly ruptured by a stainless steel pipe and a water acrosol of droplets begins to spray out of the storage tank. state all assumptions and determine the internal pressure within the water droplets produced
