Problem $1$

$2000kg.$

Water enters $2\mathrm{.}00-m^3$ tank at a rate of $6\mathrm{.}00k\frac{g}{s}$ and is withdrawn at a rate of $3\mathrm{.}00k\frac{g}{s}.$ The tank is initially half full.

a$)$ Is this process continuous, batch, or semi$-$batch? Is it transientor steady state?

b$)$ Write a mass balance for the process. Identify the terms of the general balance equation present in your equation and state the reason for omitting any terms.

c$)$ How long will the tank take to overflow?
