3. Water vapor enters a subsonic diffuser at a pressure of 70 kPa, 160°C and 180 m/s. The inlet to the diffuser is 100 cm². During passage through the diffuser the fluid velocity is reduced to 60 m/s, the pressure increases to 100 kPa, and the heat transfer to the surroundings is 0.6 kJ/kg. Determine (a) the final temperature, (b) the mass flow rate in kg/s, and (c) the outlet area in cm². P₁ = 0.7 bar T₁ = 160°C V₁ = 180 m/s (2) A₁ = 100 cm² Steam (1) Yout 0.6 kJ/kg) m2 V₂ = 60 m/s P2 = 1.0 bar
