Steam enters a nozzle at 400oC and 800 kPa with a velocity of 10 m/s, and leaves at 300oC and 200 kPa while losing heat at a rate of 25 kW. For an inlet area 0f 800 cm2, determine the velocity and the volume flow rate of the steam at the nozzle exit.
A ground level source is emitting pollution. An air sampler is located 1 km downwind and 0.5km crosswind of the source measures the concentration of the pollutant ant ground level as 10 micrograms/cubic meter.
The cash flow associated with landscaping and maintaining a certain monument in Washington, D.C., is $100,000 now and $50,000 every 5 years forever. Determine its perpetual equivalent annual worth (in years 1 through infinity)
calculate the ratio of the area to volume for unit cube,a unit sphare inscribed inside the cube,and as right cylinder inscribed inside the cube.
For some minerals color is a diagnostic property making identification rather easy. However, certain minerals can also occur in a wide variety of colors making color a poor tool for identification. List different colors for the mineral quartz lo..
a cantilever beam is additionally supported using two tierods. Both rods attach to the end of the beam. One rodcomes off at 45 degrees and attaches to the same wall that the beamis solidly fixed to
Determine the chemical oxygen demand (COD) of a mixture of 250 mg/l glutamic acid (C5H10N2O3) and 200 mg/l of glucose(C6H12O6).
In a water table aquifer bounded on the ends by rivers, the hydraulic conductivity is 50 m/day. The hydraulic heads at x = 0 and x = 1000 m are 100 m and 90 m, respectively.
Determine the minimum height on the wall to which the firefighter can project water from the hose, so that the water strikes the wall horizontally. The speed of the water at the nozzle is Vc=48ft/s.
The aluminium wire has a radius of 1.1mm. What must be the radius of the steel wire if it is to stretch the same distance as the aluminium wire, so that the two wires maintain equal lengths after the masses are attached?
On a 20 ft cantilever beam, Load W1=200 or W2=500 or both may be applied at the midpoint B or at the end of the beam C. The bending moment induced at th fixed support A, MA, will depend on the magnitude of the loads at B and C.
