A 2-m3 rigid insulated tank initially containing saturated water vapor at 1 MPa is connected through a valve to a supply line that carries steam at 400°C. Now the valve is opened, and steam is allowed to flow slowly into the tank until the pressure in the tank rises to 2 MPa. At this instant the tank temperature is measured to be 300°C. Determine the mass of the steam that has e

Answer:

5.6449

9 mpa

Explanation:

we are to determine mass of steam that has entered and also the pressure of steam.

After solving

Mass of steam = m2 - m1

= 15.925-10.2901

= 5.6449kg

Then the enthalpy of steam was calculated to be 3109.26

Using steam table, tl = 400⁰c

Hl = 3109.26

Supply line pressure = 9mpa
