A liquid-level system has the following properties: Tank dimensions: 10 ft high by 5-ft diameter Steady-state operating characteristics: Inflow, galh Steady-state level, ft 5,000 0.7 10,000 1.1 15,000 2.3 20,000 3.9 25,000 6.3 30,000 8.8 The inlet flow rate is held at 300 gal/min for 1 h and then suddenly raised to 400 gal/min. Assuming that linear interpolation is valid within inflow interval, determine the liquid-level 0 minute after the sudden increased in flowrate.

Entropy

In physics, entropy means the amount of disorder or the degree of randomness associated with a thermodynamic system. The system is not self-organized when the entropy of the system is high. For instance, when a system is at an elevated temperature, its molecules are in random motion, vibrating and colliding with each other. During this scenario, the probability of finding a molecule at a particular place twice, is low. Under this circumstance, the system can be said to be in a high entropy.
