Expert Solution
Step 1

Given,

P1 = 2000 kPa = 2 MPa

T1 = 500°C

P2 = 1000 kPa

T2 = ?

w = ? 

Step 2

From Steam Tables,

In Superheated tables,

At P1 = 2 MPa and T1 = 500°C

h1 = 3468.3 kJ/kg

In Saturated water tables,

At P2 = 1000 kPa

T2 = 179.88 °C

h2 = hf = 762.51 kJ/kg

Therefore, the exit temperature is T2 = 179.88 °C
