A pump of 80% efficiency lifts water from one large open tank to another; the difference in water surface elevations is 20 feet. The pipe is relatively smooth (f = 0.0122), and has 3 elbows, each with a loss coefficient of 2/3. The pipe is 4-inches in diameter and 40 feet long. The kinematic viscosity of water is 10-5 ft2/sec. What horsepower must be supplied to the pump in order to convey 2 CFS through the system? (Kent = .5) Assume a submerged exit.
a tape is calibrated and found to measure 100.04ft between the 0- and 100-ft marks. what measurements should be laid out to establish a horizontal distance of 682.25ft?
A 200 foot long, 2.5 feet in diameter, straight, corrugated metal storm drain pipe, is used to drain a parking lot. The elevation difference between the pipe ends is 8 feet. What velocity would be expected
design a rectangular reinforced concrete beam (tension steel only) for the span and superimposed service loads shown. use f'c=5000psi and A615 grade 60 steel. LL=3.5 k/ft over the first 12 feet of the beam
The proposed highway has two tangents of bearings N 45Degrees 54' 36" E and N 1 Degree 22' 30" W. The highway design engineer, attempting to obtain the best fit for the simple circular curve join these tangents, decides that the external is to be ..
An observer has determined that the time headways between successive vehicles on a section of highway are exponentially distributed and that 60% of the headways between vehicles are 15 seconds or greater.
A U manometer reads 20 cm air as operating fluid and a given manometric fluid. A single branch closed tube reads 35 cm connected to point 1. If P2 = 1.2 ATM calculate the pressure in point 1 and the density of the manometric fluid.
The "sea-level adjusted" pressure at the airport was about 30.57 inches of mercury. Assuming the density of air is 1.30 kg/m3 and the gas constant for air is 287. J/(kg K), calculate the temperature of the air in Fahrenheit.
Determine how many buses needed to provide service on the following route with the indicated characteristics: -Route length: 16 miles (one way) -Headway: 15 minutes -Average number of stops made during run, one direction: 22
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).
A one tenth scale model of a soap box derby car is tested in a wind tunnel. The air speed in the wind tunnel is 70m/s, the air drag on the model car is 240 N, and the air temperature and pressure are identical to those expected
Determine the strain components strainx, Strainy, and gammaxy, then sketch the deformed shape in the xy orientation, paying particular attention to the sign of the shear deformation.
A development is being planned within a 250-acre watershed. The present land use is 120 acres of pasture, with soil type B(CN=61), and the rest soil type D (CN=80). The Tc is 54 min. and the 2-year, 24-hour storm depth is 4 in.
