ENGR 323 Lecture Notes - Lecture 2: Ideal Gas Law, Viscosity
Document Summary
V = volume, n = # of moles,9. Pv = n kb t where, n = # of molecules kb = 1. 38 x 10-23 j/k. P = r t where = density. This is a good approximation for monoatomic gases at normal temperatures and pressures. The amount of energy required (per unit mass) to increase the temperature of an object by one degree. Foe ideal gases, enthalpy: h = cp t internal energy: u = cv t. Measures how sticky or thick the fluid is. A car"s fuel may specs says 10w30 referring to the viscosity. Engr 323 page 1 of oil ranging from 10 weight to 30 weight. Viscosity of a fluid is highly temperature dependent. Viscosity of liquid decreases with increase in temperature. (inversely proportional) Viscosity of air increases with increase in temperature. (directly proportional) Values of for any fluid (at any temperature) can be found in tables.
