Air at 50C with a dew point of 4C enters a textile dryer at a rate of 11.3 m3/min and leaves saturated. The dryer operates adiabatically. Use the psychrometric chart to determine the absolute humidity and humid volume of the entering air, and then use the results to determine the flow rate of dry air (kg/min) through the dryer, the final temperature of the air, and the rate (kg/min) at which water is evaporated in the dryer. (Hint: Refer to Section 8.4e.)
ACIDS AND BASES Acids: produces H+ (which is the same as protons and hydronium ion, H3O+) AND are mostly covalent compounds! H+ + OH- à H2O acid base neutralization The “protics” HCl à H+ Monoprotic ** Compounds that are monoprotic and H2SO 4à 2 H+ Diprotic diprotic are strong acids! H3PO 4à 3 H+ triprotic ** Triprotic are weak acids Ex: H2CO3 à Diprotic weak acid CH 3COOH à monoprotic weak acid Characteristics of acids: Sour Turns blue litmus paper into pink Strong Acids v. Weak acids : 2 converting pH concentration 3 Bases: substances producing OH- in an aqueous solutions AND are ALL ionic compounds Characteristics: Taste is unknown (no one has actuall
