1.An important dimensionless parameter in certain types of fluid flow problems is the Froude number defined as V/(gl)^1/2 where V is a velocity, g the acceleration of gravity, and l a length. Determine the value of the Froude number for V=15 ft/s, g=32.2 ft/s^2, l=4ft. Recalculate the Froude number using SI units ans BG
2.If the static port of an aircraft became blocked during a climb the vertical speed indicator would:
1.Remain at the previously indicated rate of climb
2.Fall to zero rate of climb indication
3.Indicate a maximum rate of climb
4.Indicate a maximum rate of descent.
Two men A and B, each having a weight of 160lb stand on a200lb cart. Each runs with a speed of 3ft/s measured relativeto the cart. Determine the final speed of the cart if:
Derive the porosity values for cubic, orthorhombic, and rhombohedral packing of spheres. Include sketches supporting your calculations of the bulk volumes of the unit cells.
determine the components of the 800 lb force f along the oblique axes a and b. also, determine the projections of f onto the a and b axes
John Adams has a $65,000 adjustable gross income from Apple Corp. and allowable itemized deductions of $7200. Mary Eve has a $75,000 adjustable gross income and $2000 of allowable itemized deductions.
Oil of a specific gravity of 0.75 is flowing through a 6-in pipe under a pressure of 15 psi. If the total energy relative to the datumplate is 8.0 ft below the center of the pipe is 58.6 ft, determine the flow rate of the oil.

North City must choose between two new snow-removal machines. The SuperBlower has a $70,000 first cost, a 20 year life, and an $8000 salvage value. At the end of 9 years , it will need a major overhaul costing $19,000.
A section of highway has a speed-flow relationship of the form "q = au^2 + bu" It is known that at capacity (which is 3100 veh/hr) the space mean speed of traffic is 28mi/hr.
consider a cylindrical copper wire 3.0mm in diameter and 3x10^4 mm long. calculate its elongation when a load of 100N is applied. Assume that the deformation is totally elastic and its Young Modulus is 110GPa.
Determine the magnitudes of the additional loads that must be applied at B and F if the resultant of all six loads is to pass through the center of the mat.
