Elementary Principles of Chemical Processes

1. What is the velocity in feet per second when 25,000lbm/hr of superheated steam at 870.23 psia and 900F flow through a pipe of inner diameter 2.9 in.? (Hint: Table B.7 is extremely useful in solving this problem.) 2. A large chamber of dry N2 at 27C and 101.3kPa. Water is injected into the chamber. After saturation of the N2 with water vapor, the temperature in the chamber is 27C. (a) What is the pressure inside the chamber after saturation? (b) How many moles of H2O per mole of N2 are present in the saturated mixture
