Q3/Air at 160 °F has a wet-blub temperature of 102 °F. Determine the relative humidity , the percentage humidity , and dew point. Note that the total pressure 14.7 ibr/in?and partial pressure 4.75 ibr/in?

Calculate and report the density, in kg m-³, of air at 1.00 atm and 10.0 °C. Take the composition of air to be 79 mol% nitrogen and 21.0 mol% oxygen. The molecular weights of nitrogen and oxygen may be taken as 28.0 g mol-¹ and 32.0 g mol-¹ respectively. State any assumptions.

Draw a graph showing water vapor pressure as a function of temperature, where relative humidity is constant at 50% (i.e. NOT saturated!). Axes have actual numbers. Upload your graph here:

Acetobacter Aceti bacteria converts ethanol to acetic acid and water under aerobic conditions.  C2H5OH + O2 --> CH3COOH + H2O.  A continuous fermentation process is proposed for the production of acetic acid using A. aceti cells immobilized on the surface of gelatin beads. The reactor is fed on a continuous basis a mixture of ethanol and water and the ethanol in the feed is consumed completely by the fermentation reaction. The flow rate of the effluent (outlet) liquid stream is 20 kgmol/h, and this stream contains 10 mol% acetic acid (the balance being water). The reactor is also being fed on a continuous basis with dry air (79 mol% N2 and 21 mol% O2) at a rate of 20 kgmol/h and the effluent gas stream is in equilibrium with the effluent liquid. The reactor operates at atmospheric pressure. The vapor pressure of water and acetic acid at the reaction temperature are 20 and 15 mm Hg respectively. What is the flow rate of the ethanol-water feed mixture and its composition? What is the…
