Textbook Question

Chapter 18, Problem 80GP

Nuclear Versus Natural Gas Energy Because of safety concerns and other constraints, nuclear power plants must be run at lower efficiencies than natural gas-fired power plants. The efficiency of a particular gas-fired power plant is 44.8% and that of a nuclear plant is 32.6%. (a) For every 1.00 kJ of mechanical work (to generate electricity) produced by the gas-fired power plant, how much energy is exhausted as waste heat? (b) How much waste heat is generated for every 1.00 kJ of work produced by the nuclear power plant? (c) What is the percentage increase of waste heat generated by the nuclear plant over the natural gas plant as a result of the lower efficiency?

6. Bending a lens in OpticStudio or OSLO. In either package, create a BK7 singlet lens of 10 mm semi-diameter and with 10 mm thickness. Set the wavelength to the (default) 0.55 microns and a single on-axis field point at infinite object distance. Set the image distance to 200 mm. Make the first surface the stop insure that the lens is fully filled (that is, that the entrance beam has a radius of 10 mm). Use the lens-maker's equation to calculate initial glass curvatures assuming you want a symmetric, bi-convex lens with an effective focal length of 200 mm. Get this working and examine the RMS spot size using the "Text" tab of the Spot Diagram analysis tab (OpticStudio) or the Spd command of the text widnow (OSLO). You should find the lens is far from diffraction limited, with a spot size of more than 100 microns. Now let's optimize this lens. In OpticStudio, create a default merit function optimizing on spot size.Then insert one extra line at the top of the merit function. Assign the…
