Problem HW$3\mathrm{.}6$

An insulated, rigid tank whose volume is $10f{t}^3$ is connected by a valve to a large steam

line through which steam flows at $500lb\frac{f}{i}{n}^2,800F.$ The tank is initially evacuated.

The valve is opened only as long as required to fill the tank with steam to a pressure of

$500lb\frac{f}{i}{n}^2$

a$)$ Determine the final temperature of the steam in the tank, in $F(1114\mathrm{.}1F)$

b$)$ Determine the final mass of steam in the tank, in lbm$.$

$(5\mathrm{.}42lbm)$

Tips and procedure:

Sketch the system, write assumptions and given values

Evacuated $=$ zero mass contained inside tank

Interpolate if needed
