Problem 1 [10 points] Water at 22C enters a 2 m tank at a rate of 6 kg/s and is withdrawn at a rate of 3 kg/s. The tank is initially half full. (a) Draw a block flow diagram for the process. Is this process continuous, batch or semi- batch? (b) Is it transient or steady state? (c) What is the initial mass of water in the tank? (d) What is the volumetric flow rate of the stream leaving the tank? (ec) Write the overall mass balance for the process. Simplify the equation and indicate assumptions if necessary. (f) How long will the tank take to overflow
