Question:


How many cubic feet per minute of entering air is needed to evaporate 10 lb of water per hour from a rayon, if the air enters at 80 deg F and 25% humidity and leaves at 170 deg F and 55% humidity. The operating pressure is 14.3 psia.
A. 22.54
B. 12.68
C. 23.76
D. 16.28

Answer:


Step 1

The dry bulb temperature and relative humidity of the inlet air is 80 F and 25%, respectively. The specific volume and humidity ratio at the given parameters is calculated from psychrometric chart. The values are:

QUESTION 6 (a) The bar shown in Figure Q2(a) is subjected to tensile load of 150 Kn. If the stress in the middle portions is limited to 160 N/mm², determine the diameter of the middle portion. Find also the length of the middle portion if the total elongation of the bar is to be 0.25 mm. E E = 2.0 + 105N/mm².

The term covers a large and diverse body of processes. Many oxidation-reduction reactions are as common and familiar as fire, the rusting and dissolution of metals, the browning of fruit, and respiration and photosynthesis—basic life functions.  Oxidation is the  gain  of oxygen. Reduction is the  loss  of oxygen. Most oxidation-reduction (redox) processes involve the transfer of oxygen atoms, hydrogen atoms, or electrons, with all three processes sharing two important characteristics: (1) they are coupled in any oxidation reaction a reciprocal reduction occu...
