A tank contains 20 percent liquid water and 80 percent steam by volume at 200 degrees celsius. Steam is withdrawn from the top of the tank until the fluid remaining in the tank is at temperature of 150 degrees. Assuming the tank is adiabatic and that only vapor is withdrawn, compute
1. the pressure in the tank finally
2. the fraction of vapor and liquid in the tank finally
3. the fraction of the total water present initially that was withdrawn
