Question: [textbook (5th edition): Chapter 15: Problem D6 - p 646] Water at 60C and 0.95 bar is evaporating into a 12.0cm-long tube (also at 60C
[textbook (5th edition): Chapter 15: Problem D6 - p 646] Water at 60C and 0.95 bar is evaporating into a 12.0cm-long tube (also at 60C ) and diffusing through a stagnant layer of air. The device is illustrated in Figure 152 in the textbook ( p83 in 5th edition). a. Calculate the flux of water vapor if convection is included. b. Calculate the value of the molar reference velocity. c. If the tube is 1.5cm in diameter, calculate the grams of water evaporated per hour. d. Calculate flux of water vapor if convection is not included (a calculation that is expected to be incorrect for this example). Data: At 60C,Dwater-air=3.05105m2/s,VPwate=149.5mmHg
