A normal shock is observed to stand at x=0.6 m. Calculate (a) mass flow rate (kg/s). Plot, from inlet to exit along the x axis of the C-D duct, (b) Mach number ,(c) static pressure (pa) , (d)total pressure (pa), (e)static temperature ( oK), (f) total temperature( oK), and (g) entropy (kJ/kgoK) distr

Amass of m 1.5 kg of steam is contained in a closed rigid container. initially the pressure and temperature of the steam are: p 1.5 mpa and t 240°c (superheated state), respectively. then the temperature drops to t2= 100°c as the result of heat transfer to the surroundings. determine: a) quality of the steam at the end of the process, b) heat transfer with the surroundings. for: p1.5 mpa and t 240°c: enthalpy of superheated vapour is 2900 kj/kg, specific volume of superheated vapour is 0. 1483 m/kg, while for t 100°c: enthalpy of saturated liquid water is 419kj/kg, specific volume of saturated liquid water is 0.001043m/kg, enthalpy of saturated vapour is 2676 kj/kg, specific volume of saturated vapour is 1.672 m/kg and pressure is 0.1 mpa.
