Question

Question 1

Using the tables for water determine the specified property data at the indicated state.
For H₂O at p = 0.7 MPa and v = 0.51 m³/kg, find u in kJ/kg.
Note: Round up the answer to 2 decimal places.

Question 2

Using the tables for water determine the specified property data at the indicated state.
For H₂O at p = 10 MPa and u = 990 kJ/kg, find h in kJ/kg.
Note: Round up the answer to 2 decimal places.

Question 3

Using the tables for water determine the specified property data at the indicated state.
For H₂O at T = 40 °C and X = 33 %, find v in m³/kg.
Note: Round up the answer to 2 decimal places.

Question 4

Using the tables for water determine the specified property data at the indicated state.
For H₂O at p = 0.7 MPa and v = 0.58 m³/kg, find h in kJ/kg.
Note: Round up the answer to 2 decimal places.

Question 5

Five kg of water at 180°C fill a closed container having a specific volume of 0.08 m³/kg. If the water at this state is a vapor, determine the pressure, in bar. If the water is a two-phase liquid–vapor mixture, determine the quality.
Note: Round up the answer to 2 decimal places.
