Phase 1:
Initially ALL Valves A, B, C, D, E and F are closed.
ALL Tanks A, B, C, D, E are separated and each sealed from the atmosphere.
Tank E initially has 2’ of air @ 32.476 psi. 15’ x 27’ x 2’
Tank C and Tank B initially contain air @ 32.476 psi
Pipe K initially is 12” id x 5’ @ 32.476 psi
Tank A: 15’ x 27’ x 50’ 20,250 ft3
Tank D: 100’ x 100’ x 100’ clear water
Phase 2:
Valve D and F are opened 1^{st.}
Valve E, A and B are opened 2^{nd}.
Valve C remains closed.
When Tank C and Pipe K have exhausted all air, valves A, B and E close simultaneously. Valves F and D remain open.
problem 1: What is the elapsed time for air in Tank C and Pipe K to move to Tube B?
problem 2: What is the height and psi of Air in Tank E and Tank A?
problem 3: What are the final height and psi of air column Tube B Section F and G?
