How accurately would each 100-ft distance have to be measured so that the 95% error would no exceeded +-0.24ft in a total distance of 4000ft
A 600 MWe power plant has an efficiency of 36% with 15% of the waste heat being released to the atmosphere as stack heat and the other 85% taken away in the cooling water.
The slope of the channel So=.15% and the Manning n=.038. Estimate the depth y2=100m upstream of a section where the flow depth y1=2.2m Using a) the direct integration method and b) the standard step method.
A 12 foot W14 X 22 column with pinned ends is axially loaded. The max load it can carry is 34 ksi. Determine (a) Euler buckling stress, (b) Euler buckling load. (A = 6.49 in^2) (ry = 1.04 in) (Iy = 7.00 in^4)
A bar of monel metal (length L=9 in., diameter d=0.225 in.) is loaded axially by a tensile force P. If the bar elongates by 0.0195 in., what is the decrease in diameter d What is the magnitude of the load P
