Problem 149P

Air at a total pressure of 90 kPa, 15°C, and 75 percent relative humidity is heated and humidified to 25°C and 75 percent relative humidity by introducing water vapor. If the mass flow rate of dry air is 4 kg/s, the rate at which steam is added to the air is

(a) 0.032 kg/s

(b) 0.013 kg/s

(c) 0.019 kg/s

(d) 0.0079 kg/s

(e) 0 kg/s

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.
