Problem 5.17

A tank used to dampen liquid flow rate surges is known to exhibit second-order dynamics. The input flow rate changes suddenly from 120 to 140 gaVmin. An operator notes that the tank level changes as follows: Before input change: level Four minutes later: level Forty minutes later: level 6 ft and steady 11ft 10ft and steady (a) Find a transfer function model that describes this process, at least approximately. Evaluate all parameters in your model, including units. (b) Is your model unique? Why or why not?

Step-by-Step Solution:
Step 1 of 3

The Price Level and Inflation—9.2.2016 Inflation – the growth in the overall level of prices in an economy (the average of price level changes for all goods increases). Deflation (opposite of inflation) – occurs when overall prices fall (the average of price level changes for all goods decreases). Consumer price index (CPI): a measure of the price level based on the consumption pattern of a typical consumer.  Price index = (basket price/basket price in base year) x 100 o Basket price – price of everything that the consumer uses. 9.7.2016 Inflation rate (i) = tP -t – 1Pt – 1100%  Change in CPI You can use inflation rate to compare prices across time.  Price today = price earlier x (price level today/price level earlier)  Ex.
