Homework 1 1. The density of a sample of sea water is 1.99 slug/ft3. What is its SI value. 2. A cubic meter of air at 10lkPa and 15 degrees C weighs 12 N. What is its specific volume? 3. The specific volume of a certain perfect gas at 2OOkPa and 40 deg. C is 0.65 m3/kg. What is its gas constant and molecular weight? 4. One cubic meter of N2 at 40 deg. C and 340kPa is compressed isothermally to 0.2m3. What is the pressure of the nitrogen in this reduced volume? 5. Anderson problem 1.4. 6. Anderson problem 1.5. 7. The Morton number, Mo, used to correlate bubble dynamics studies, is a dimensionless combination of acceleration of gravity, g, viscosity, p, density, p, and surface tension coefficient, Y. If Mo is proportional to g, find its form.

Unformatted text preview: N For a flat plate, 8 = 0 in Eqs. (1.7) - (1.1 1). Hence, r .

If Mo is proportional to g, find its form. 1 1 Solution: The relevant dimensions are {g) = {LT~), {p) = {ML- T }, { p ) = {IvL-~}, and { Y } = {MT"). To have g in the numerator, we need the combination: Solve for a = 4, b = -1, c = -3, or: Mo = - gp4 Ans. py3...
