A liquid-level system has the following properties: Tank dimensions: 10ft high by 5 -ft diameter Steady-state operating characteristics: The inlet flow rate is held at 300gal/min for 1h and then suddenly raised to 400gal/min. Assuming that linear interpolation is valid within inflow interval, determine the liquid-level 2.8 minute after the sudden increased in flowrate. Round your answer to 2 decimal places
