Required information NOTE: This is a multi-part question. Once an answer is submitted, you will be unable to return to this part. A 3ft3 rigid tank initially contains saturated water vapor at 300F. The tank is connected by a valve to a supply line that carries steam at 200 psia and 410F. Now the valve is opened, and steam is allowed to enter the tank. Heat transfer takes place with the surroundings such that the temperature in the tank remains constant at 300F at all times. The valve is closed when it is observed that one-half of the volume of the tank is occupied by liquid water. The properties of water are v1=6.4663ft3/bm,u1=1099.8Btu/lbm,vf=0.01745ft3/lbm,vg=6.4663ft3/lbm,uf=269.51Btu/lbm,ug=1099.8 Btu/lbm, and hi=1216.92Btu/lbm. etermine the amount of steam that has entered the tank. (You must provide an answer before moving on to the next part.) he amount of steam is
