A fluid of density rho flows steadily downward between the two vertical, infinite, parallel plates. The flow is fully developed and laminar. Make use of the Navier Stokes equation to determine the relationship between the discharge and the other parameters involved, for the case in which the change in pressure along the channel is zero.
Determine the required size of new Schedule 40 steel pipe to carry 0.5 cfs (Q = 0.5 cfs) of water at 160o F with a maximum pressure drop of 10 psi per 1,000 ft.
An insurance sales representative sells policies to 5 men, all of identical age and in good health. According to the actuarial tables, the probability that a man of this particular age will be alive 30 years hence is 2/3.
If the flowrate is Q = 25 ft^3/s and the upstream depth is 2 ft, determine the downstream depth. Sketch the specific energy diagram and indicate its important characteristics. Note that the specific discharges are different.
assume that the whole twisting moment is taken by the bone. If the humerus can withstand a shear stress Tmax=70.0 MPa, determine the maximum force the hand can apply without fracturing the humerus. The length of the forearm is 360 mm.
a newly designed car has a 9.2 ft wheelbase, is rear wheel drive, and has a center of gravity 18 inches above the the road and 4.3 ft behind the front axle. the car weighs 2450 lb, the mechanical effciency of the drivetrain is 90%, and the wheel r..
nighttime traffic on a single lane of rural highway is light, with a flow of 40 vehicles/hour , and is well described by a Poisson arrival process. A racoon dashes across the road, without looking at a speed of 12 mph.
determine the horizontal spacing of the vertical drains if the drains are installed in triangular grid to reach 90% of primary consolidation in 1.5 years after the commencement of fill placement
What return period must an engineer use in the design of a bridge opening for a 50% risk that flooding will occur at least once in two consecutive years? Repeat for a risk of 100%.
Consider the steady-flow energy equation applied to the given extrusion process. Since the die is horizontal then there will be no change in potential energy from inlet to outlet. Hence the potential energy terms can be neglected.
The space truss shown is supported by a ball-and-socket joint at D and by short links at A and C. Determine the support reactions and the force in each member of the space truss.
Determine the horizontal component of reaction that the pin A exerts on the two-member frame. Set F = 500 (Find Ax) Determine the vertical component of reaction that the pin A exerts on the two-member frame.
How much subsidence would be expected from an elastic confined aquifer that has a specific storage of 2.0*10^-6 (ft^-1), a decline in pressure of 200 (lbs/in^2), and aquifer thickness of 400 ft, and a porosity of 32 percent
