Shaquille O Neal, who is listed as 7`1" tall is out of the NBA Playoffs and so has time to visit is pool. If he stands vertically in the water, completely submerged, determine the difference between the pressure is acting at his head and at his toes, in Lbf/in^2.
a low broad crest weir is installed in a wide, rectangular channel to reduce the flow velocity. the channel is 60ft wide, the channel slope is 1 to 2000. Manning's roughness coefficient n=0.014. the discharge per unit channel width is q=60 cfs/ft.
For each subcritcal, critcal, and supercritcal flows, comment on the values for the Froude number, the depth of the water channel, and the specific energy. How do these values compare to each other for each of the flow types
A tray rests on an extendible arm consisting of two steel tubes with two different outer diameters. The downward force at the tray center F0 = 1000 N. Determine the downward deflection of the tray center and the tilt angles of the tray about each ..
The new owners propose to flush the pond into their discharge pipe leading to the Atlantic Ocean, which has a salt concentration above 30,000 mg/L. What flow rate of fresh water (in m3/s) must they use to reduce the salt concentration
The velocity of the bed is limited to a maximum value of 150mm/s to the right and 300mm/s to the left; the acceleration is successively equal to 150mm/s^2 to the right, zero 150 mm/s^2 to the left, zero, etc.
At what temperature does the liquid solidify? What is the composition of this last remaining liquid phase?
What is the Federal Express philosophy toward quality? What specific elements/actions has FedEx implemented in its quality improvement history?
Biota can uptake and bioconcentrate compounds through vapor phase absorption. For example, leaves exposed to elemental mercury vapors will absorb the mercury into the aqueous phase and the lipid phases of the leaves. Kow for mercury = 4.17.
The beam is to be hoisted using two chains. Determine the magnitudes of force and acting on each chain in order to develop a resultant force of 500 directed along the positive axis. Set = 41
a navel gun (E= 30,000 ksi and G = 11,600 ksi) with a bore of 16 in. develops a maximum internal pressure of 20,000 psi. Determine a. the minimum outside diameter required if the maximum tensile stress permitted in the gun barrel is 36,000 psi.
An equal-tangent sag curve has its PVI at station 10+00 and elevation at 138 ft. Directly above the PVI the bottom of an overpass structure is at elevation 162 ft. The PVC is at station 4+00. If the initial grade is -4.0%
Theis Method plot drawdown vs. time for 4 observation wells, 5, 50, 100, 500 meters from well pumping at constant rate of 300 m^3/day in sandy confined aquifer. b=12 m, K=25 m/day, and S=10^-4.
