Final answer:
To find the pressure for T = 140ᵒC and v = 0.5 m³/kg using the steam tables for water, you need to refer to a steam table for water. The location of the point can be shown on a T-v diagram by plotting the temperature on the x-axis and the specific volume on the y-axis, and then marking the corresponding point.
Step-by-step explanation:
To find the pressure for T = 140ᵒC and v = 0.5 m³/kg using the steam tables for water, you need to refer to a steam table for water. The steam table will provide you with the pressure corresponding to the given temperature and specific volume. The location of the point can be shown on a T-v diagram by plotting the temperature on the x-axis and the specific volume on the y-axis, and then marking the corresponding point.
