A flowrate of 1.0 L/min of oil of specific gravity 0.92 exists in this pipeline. Is this flow laminar? What is the viscosity of the oil? For the same flow in the opposite directio, what manometer reading can be expected?
A horizontal pre-stressing force of 750kn is applied to a rectangular concrete beam to be used as a structural member of a traffic bridge. The beam has a depth of 500mm and a width of 250mm. The force is applied at a distance of 80mm below the sec..
The rigid bar of negligible weight is supported as shown. Find the stress in each rod if the temperature rises DeltaT after a load P is applied. Use the following data: area of steal rod 320mm2, bronze rod 1300mm2, thermal expansion coefficient Al..
Of this total, 2000 acres are residential(CN=68), 500 acres are industrial (CN=88), and 2500 acres are forest with good cover (CN=55). For a design storm of with a total precipitation of 7 inches, estimate the direct runoff in inches.
What pressure gradient is required to accelerate water vertically upward in a vertical pipe at a rate of 0.5g
A wood board with a 2in. by 4in. cross section is subjected to a tensile load of 100 lb. Determine the average normal stress and average shear stress developed in the wood fibers that are oriented at 30 degrees with the axis of the board.
An equal tangent vertical curve connects a -2% and a +3% grade. The low point of the curve is at elevation 297.88 ft. If the PVI is at elevation 295 ft, what is the design speed of the curve
Also, at the failure cross sections the diameters are found to be 0.731 in., 0.645 in., and 0.587 in., respectively. Determine the percent elongation and percent reduction in area of each specimen.
A barge has the trapeziodal shape and is 22 m long into the paper. If the total weight of barge and cargo is 350 tons, what is the draft H of the barge when floating in sea water
The specific heat (C sub p) of aluminum is 0.214 calories per gram degrees Celsius (0.214 cal/g-C). If a cube of aluminum with a mass of 13.6 kg exhibits a change in temperature of +30 degrees Celsuis, what is the resultant thermal energy
Draw the shearing force diagram and the moment diagram of the following problem. The beam is indeterminate. You need to integrate the moment twice to get a formula for the deflection v(x).
for this purpose replace this force by its equivalent of two forces at At Ft parallel and Fn perpendicular to the beam. Determine Ft and Fn.
The system is released from rest with no slack in the cable and the spring stretched 120 mm. The coefficient of kinetic friction between the 10 kg cart is 0.25 and the mass of block m is 6.3 kg.
