The figure shows one-half of a universal coupling known as the Hooke's joint. The coupling is acted on by the three couples shown:
(a) the input couple consisting of forces of magnitude P,
(b) the output couple C0, and
(c) the couple formed by bearing reactions of magnitude R. If the resultant of these couples is zero, compute R and C0 for P = 600 lb.
If the length of the river connection between the two lakes is equal to 3km and the velocity in the river is equal to 0.4 m/s, determine the concentration of UBOD in the effluent from the second lake.
What is the definition of an ideal fluid? What is the dynamic viscosity of an ideal fluid? Can an ideal fluid flow be supersonic? Explain.
What does it mean to overproduce or under produce a product?
A bridge has been constructed between the mainland and an island.The total cost (excluding tolls) to travel across the bridge isexpressed as C = 50 + 0.5V, where V is the number of veh/h and C isthe cost/vehicle in cents.
A culvert under a road must be 35m long, have a slope of 0.0035 and carry 4m^3/s. The crown of the roadway is 4.2m above the culvert invert. Assume the outlet will discharge freely.
At the inlet the steam is at 1 MPa and 320 C, and leaves the turbine at 20 kPa. The work output of the turbine is measured to be 600 kJ/kg (of steam passing through the turbine).
Solve the problem using the Darcy Weisbach equation and the Colebrook-White equation. Size the pipe to the nearest inch. Assume the water temp is 80 degrees F.
One lbm air at 15 psia is mixed with 2 lbm air at 30 psia, both at 540 R, in a rigid, insulated tank. Find the final state (P, T) and the entropy generation in the process.
Colette Lake has a surface area of 103 ha and a mean depth of 8 m. The pH of the water is 7.6. The lake receives surface water from a lake upstream, rainfall, and diffuse groundwater input. Atmospheric inorganic N deposition is insignificant.
The only losses of total phosphorus for the lake are settling and fluching throught the lake's outlet. Assume the outflow rate is 212 km^2/year and the sediment area is 10,500 km^2.
A smooth nozzle with a tip diameter of 2 inches terminates a 6 in waterline. Calculate the mean velocity of efflux from the nozzle when the velocity in the line is 10 ft/s.
This is a Photogrammetry question that im having difficulty with: Given the parameters for a 2-d similarity transformation, how would you compute the equivalent rigid body transformation parameters?
