A central receiver in a solar power plant absorbs a concentrated solar flux from heliostats. However, losses from free convection and radiation lowers the collection efficiency. Consider a receiver with a diameter of 7 m and a height of 12 m that has an emissivity of 0.25 and a surface temperature of 800 K. If the solar flux is 100,000 W/m2, find the collection efficiency. The ambient air and surroundings are at a temperature of 300 K. Assume the curvature of cylinder has a negligible effect on boundary layer development and use the Churchill and Chu correlation to determine the Nusselt number.

The central receiver of a solar power plant is in the form of a
cylinder 7m in diameter and 13 m high. A tower supports the
receiver high above the ground, and solar radiation is reflected to
the receiver by rows of reflectors at ground level. The operating
temperature of its surface is 700K and the temperature of the still
ambient air is 300 K. The total irradiation of the collector is 20
MW.

Concentrated solar power is a method of using the Sun's light to
produce useful energy on Earth. A large system of mirrors collects
light during the day and focuses it on a target which is raised to
a high temperature. The energy delivered to the target is then used
to generate steam which runs turbines to produce electricity. The
mirrors do not have to be circular, and for some designs they focus
light along a line rather than to a...

Florida Power and Light has committed to building a solar power
plant. An engineer that works in FLP, has been tasked with
evaluating the three current designs. FLP uses an interest rate of
10% a 20 years horizon.
Design 1: A field of “flat” solar panels angled to best catch the
sun will cost $87 million initially with firstyear operating costs
at $1.8 million, growing $250,000 annually. It will produce
electricity worth $7.8 million the first year and will increase...

(a) Show that the solar flux densities (irradiances) from the
sun, F1 and F2, relate one another as the inverse square of their
distances from it, that is: 2 2 1 2 1 F = (r /r ) F .
(b) Use the answer to (a) to solve the following question: The
orbit of Mars around the sun is more eccentric than that of the
earth. At its closest Mars is 200 million kilometers from the sun,
and at its...

Problem:
An electric company has committed to building a solar power
plant. An engineer tasked with the company has been tasked with
evaluating three solar power generation technologies. The power
company uses an interest rate of 10% and a 20-year planning horizon
for choosing the project that best fits its budgetary and financial
goals.
Design 1: Flat Solar Panels: A field of flat solar panels angled
to best catch the incident solar radiation wis expected to yield a
power of...

An electric utility is considering a new power plant in northern
Arizona. Power from the plant would be sold in the Phoenix area,
where it is badly needed. Because the firm has received a permit,
the plant would be legal; but it would cause some air pollution.
The company could spend an additional $40 million at Year 0 to
mitigate the environmental problem, but it would not be required to
do so. The plant without mitigation would cost $269.63 million,...
