The closed cylindrical container in the figure initially contains $50$ L of water at $20$ C at $1$ atm pressure. The system is heated by an electric resistance drawing $10$ Ampere under $220$ V voltage. $1000\frac{W}{m}2$ of heat escapes from the container. Since the diameter of the bottom of the container is $D=40cm,$ for the degree of dryness $x=0\mathrm{.}75$;

a$)$ Find the time required for this process.

b$)$ Find the final temperature.

c$)$ Find the final pressure.
