L Flow in an orifice

Consider a steam flow through an orifice (see Exercise 4.Q).

• Atmospheric state: P a = 1 bar Tˆ a = 20 ◦C • Steam pressure at inlet: P1 = 6.261 bar • Steam pressure at outlet: P3 = 6.030 bar • Specific constant of the steam: r = 0.4615 kJ/(K kg) • Mass flow de steam: M˙ = 3.03 kg/s

• Calculate the exergy loss.
