In the United States, electricity is sold using the SI units of kilowatt (kW) or megawatt (MW), and fuel for power
generation stations is generally purchased using English units, e.g., British thermal unit (Btu), gallon (gal), and ton. An industrial power plant has an average annual load of 100 MW (electrical). If the overall thermal efficiency is 33% (based on HHV), what is the annual cost of fuel if the plant is fired with (a) natural gas, (b) No. 2 fuel oil, and (c) bituminous coal? Use the data from Tables 2.2, 2.7, and 2.13. Assume the cost of natural gas is $5/million Btu, the cost of No. 2 fuel oil is $3/gal, and the cost of bituminous coal is $60/ton (1 ton = 2000 lbm)
The amount of time it takes for a pendulum to swing “to-and-fro” through one complete cycle is called the “period” and is calculated using the following equation:
where
T = period in seconds, I = mass moment of inertia, m = mass of pendulum in kilograms
g = gravitational acceleration, 9.8 m/s2, h = effective length of pendulum in meters
What is the appropriate unit for I if the preceding equation is to be homogeneous in units? Please show all of your work.
