Steam at 1.2 mpa and 320°c enters a diffuser steadily with a velocity of 150 m/s, and leaves at 3 mpa with a velocity of 50 m/s. during transit through the diffuser, 3 kj/kg of heat is lost to the atmosphere. a) sketch the diffuser and label the states. b) what is the specific enthalpy of the steam entering the diffuser? c) determine the specific enthalpy of the steam at the exit. d) determine the exit temperature of the steam. e) find the change in specific entropy of the steam as it passes through the diffuser.
