A solar collector design consists of an inner tube enclosed concentrically in an outer tube that is transparent to solar radiation. The tubes are thin walled with inner and outer diameters of 0.08 and 0.10 m, respectively. The annular space between the tubes is completely enclosed and filled with air at atmospheric pressure. Under operating conditions for which the inner and outer tube surface temperatures are 80 and 30°C, respectively, what is the rate of convective heat loss per meter of tube length across the air space?

A capacitor consists of two concentric spherical shells. The
outer radius of the inner shell is a = 0.1 m and the inner radius
of the outer shell is b = 0.2 m. a. What is the capacitance, C, of
this capacitor? b. Suppose the maximum possible electric field at
the outer surface of the inner shell before the air starts to
ionize E max(r=a) = 3.0*10^6 V/m . What is the maximum possible
charge on the inner capacitor? c....

Solar Collector Field: This design uses a series of Fresnel
lenses and concave mirrors to concentrate solar radiation onto a
boiler mounted on a tower. The boiler then produces steam, which
then is used to generate electricity. This system is expected to
yield a power of 3.3 MW and will cost $91 million initially with
first-year operating costs of $3 million, growing 350,000 annually.
It will produce electricity worth $9.7 million the first year; this
revenue stream is expected to...
