Research and briefly identify the energy conservation measures that reduce a building's energy use by reducing one or more of the heating/cooling/electrical loads experienced by that building. (hint : ground source heat pumps, etc. do not reduce the building load, they merely are a more efficient manner of meeting the building load.)
Then select one of the conservation measures you have identified above, and prepare a written report, 1500 words in length, and illustrated as required. Make sure you follow guidelines re: footnotes, identification of all sources and plagiarism.
The report must summarise how the measure reduces building load and hence saves energy, what building science principles are involved, how successful the measure is in practice, what limitations there are in using this measure, and how much can typically be saved.
If this rod is to be used again with an initially straight axis, determine the maximum permissible deflection that may be allowed during testing procedures. Young's Modulus = 210 kN/mm2 and Yield stress of the steel= 240 N/mm2.
An eighteen inch diameter sandstone column is subjected to an axial compressive force of 2x10^6 lb / ft. Find the factor of safety based on the ultimate compressive force. For the ultimate compressive stress of sandstone=85Mpa.
Create a depreciation schedule showing annual depreciation amounts and end-of-year book values for a $26,000 asset with a 5 year service life, using the MACRS depreciation method.
A nuclear facility in a coastal region is built to withstand ocean wave forces. Suppose the annual maximum wave height of the ocean waves (above the sea level) is a lognormal random variable with mean height of 4.0 meters and a c.o.v. of 0.8
A square with the dimensions of .02m by .02m by .5m is attatched to a solid surface. If the forces on the rod are too large, it will either crush or be sheared off where it is atatched to the solid surface.
A thin tube of 1/8 in thickness has a mean diameter of 6 in. What is the maximum torque the tube can transmit if the allowable normal stress in compression is 10 ksi
To float a 160 pound man using helium balloons (assume 0.52 cubic feet per inflated balloon). How many balloons would it take? Assume density of air is 1.29 kg/cubic meter and the density of helium is 0.179 kg/cubic meter.
how do i solve this problem a 14 in diameter rod must be machined on a lathe to a smaller diameter for use as a
If a certain watershed received 1,250 mm of rain during a year, stored 150 mm of water in its soil mantle, and lost 400 mm of water downstream, how much water (in mm) was lost to the atmosphere (mainly through plants)
A storm sewer is carrying snow melt containing 1200 mg/L of NaCl into a small stream. The stream has a naturally occurring NaCl concentration of 20 mg/L. If the storm sewer flow rate is 2000 L/min and the stream flow is 2.0
Determine the shear stress in a 25 × 50 cm rectangular section if the shear force is 20 KN and torsional moment is 10 KN m at service loads. Assume M20 mix and 0.75% tension reinforcement at an effective cover of 50 mm.
