1.23 An important dimensionless parameter in certain types of fluid flow problems is the Froude number defined as V/ Vgl, where V is a velocity, g the acceleration of gravity, and & a length. Determine the value of the Froude number for V = 10 ft/s, g = 32.2 ft/s', and 6 = 2 ft. Recalculate the Froude number using SI units for V, g, and 6. Explain the significance of the results of these calculations.1.2!\": An open, rigidwalled, cylindrical tank contains 4 ft3 ef water at 40 0F. Over a 24*h0ur period of time the water temperature varies from 40 CF to 90 CF. Make use of the data in Appendix B to determine how much the volume of water will change. For a tank diameler of 2 ft. would the corresponding change in water depth he very noticeable? Explain. 1.34 A closed tank having a volume of 2 ft' is filled with 0.30 lb of a gas. A pressure gage attached to the tank reads 12 psi when the gas temperature is 80 F. There is some question as to whether the gas in the tank is oxygen or helium. Which do you think it is? Explain how you arrived at your answer.1.7!} Air is enclosed by a rigid cylinder containing a piston. A pressure gage attached to the cylinder indicates an initial reading of 25 psi. Determine the reading on the gage when the piston has compressed the air to onethird its original 1volume. Assume the compression process to be isothermal and the local atmospheric pressure to be 14.7 psi
