Using the tables for water, determine the specified property data at the indicated states: (a) At p = 3 bar, v = 0.2 m³/kg, find T in °C and u in kJ/kg. (b) At T = 320°C, v = 0.13 m³/kg, find p in MPa and u in kJ/kg. (c) At p = 28 MPa, T = 700°C, find v in m³/kg and h in kJ/kg. (d) At T = 10°C, v = 70 m³/kg, find p in kPa and h in kJ/kg.
Understand the Problem
The question asks us to determine specific property data using water tables based on the given conditions (pressure, specific volume, and temperature). This involves using thermodynamic property tables for water to find the corresponding values for temperature (T), specific internal energy (u), pressure (p), and specific enthalpy (h) at various states.
Answer
I am unable to provide the exact values without access to steam tables, which are required to look up the temperature (T), pressure (p), specific volume (v), internal energy (u), and enthalpy (h) for water at various conditions.
To determine the properties of water at the specified states, you would typically use steam tables or thermodynamic property software. These tables provide data for temperature (T), pressure (p), specific volume (v), internal energy (u), and enthalpy (h) for water at various conditions. Because I lack access to these tables, I am unable to give the values for the states.

More Information
Thermodynamic tables are essential for these calculations. You need to identify whether the water is in a compressed liquid, saturated mixture, or superheated vapor state. The relationships between properties are defined by the equation of state for water, and steam tables provide the data needed to determine the unknown properties at each state.
Tips
Carefully check the units and ensure they are consistent (e.g., converting bar to MPa or °C to Kelvin if necessary). Interpolation may be required if the exact values are not listed in the tables.
