A lubrication system in a coal mining dragline, pumps 140 mL/s of oil with a density of 810 kg/m3 and viscosity of 0.01 kg/m.s, across the full height and length of the machine. Downstream of the storage tank and 5 m above the ground, at a point T in the three millimetre diameter pipeline, the pressure is 1.55 kPa. The lubricant flows downstream to the head of the boom at a point H, 36.5 m above the ground, where it passes through a gallery with a diameter of 0.02 metres. The total flow then moves to a point W on the traction drive two metres off the ground, and travels through a nine millimetre diameter conduit. Ignoring all friction and minor losses, determine the pressures at points H and W.
The 75 lb block is released from rest 5 ft above the plate. Determine the compression of each spring when the block momentarily comes to rest after striking the plate.
Develop a simple urban constructed wetland design.
The central angle is 35 degrees, the superelevation is 0.08, and 20.6 ft is cleared (for sight distance) from the inside edge of the innermost lane. Determine a maximum safe speed (assuming current design standards) to the nearest 5 mi/h.
Determine the rate at which heat is added in the boiler, the power required to operate the pumps, the net power produced by the cycle, and the thermal efficiency.
the maximum degree of curvature can be at most 6.0 and the superelevation can be at most +6.0%. Design the ramp for the highest horizontal curve design speed given the constraints.
What is the concentration of tracer in the reactor 1 h after tracer addition is terminated? The reactor had an initial concentration of tracer of 1.0 mg/L when tracer addition commenced.
If the tensil testing machine can apply no more than 925 lbs. of force to the specimen, calculate the maximum rod diameter that should be used. (precision 0.000)?
Assume you are observing traffic in a single lane of a highway at a specific location. you measure the average headway and average spacing of passing vehicles as 3 seconds and 150 ft, respectively. calculate the flow, average speed, and density of..
Discuss the different agencies, institutes, centers, different environmental companies that are active in UAE.
The ship has a total weight of 155,000 tons, length = 1,600 feet and a beam = 150 feet (assume that it is the shape of a rectangular box). Calculate the height above the waterline of its center of Gravity (G).
what is the engineering ethics course where to write about any engineering ethical case and discuss the ethical issue?
a) The maximum flow rate that can be achieved without cavitation occurring in the piping system. b) The maximum elevation of the highest point of the piping system to avoid cavitation.
