where G is the shear modulus, ₁ is the angle of twist per unit length, T is torque, and L is the length of the median line.
In this case, i = 1, 2, 3, and T; represents the torque in leg i. Assuming that the angle of twist per unit length for each
leg is the same, show that

Consider a new 1800 MW power plant that burns dry sub-bituminous coal in a PC-wall-fired,
wet bottom furnace with plant efficiency of 39%. Use the emission factors in your lecture
notes to determine the emission rates of all particulates, PM10, SOx, NOx and CO in ton per
year. No gas treatment equipment was installed.
A lignite-fired power plant was designed to produce electricity at a maximum capacity of 750
MW. By average over a year, the plant is operated at 35% plant efficiency and 65% of the
design capacity. Assume that the entire amount of sulfur in lignite coal entering the plant is
converted to sulfur dioxide (SO2). The power plant is equipped with an 85% efficiency SO2
removal unit. Use the engineering calculation approach and the coal information (dry basis)
found in your lecture notes to determine emission rate of SO2 in lb/hr and in lb/BTU input.

- An industry is proposing to construct a new coal-fired power plant that produces 2300 MW electricity with efficiency of 39%. Coal has a heating value of 10,750 Btu/lb, and contains a sulfur content of 2.4%. It is expected that 95% of sulfur will be converted to SO2. The New Source Performance Standards (NSPS) limits the SO2 emission rate from any coal-fired power plants to 1.2 lb/ 106 Btu heat input. Use the engineering calculation approach to determine the followings. a) Coal consumption rate in lb/hr b) SO2 emission rate in lb/hr c) Determine if the newly proposed power plant is required to install a flue gas desulfurization (FGD) process for SO2 removal from the flue gas. What percent SO2 removal is required?arrow_forwardA stack gas at 1 atm and 440oC contains 1100 ppm NO2.

The power plant produces 350 MW of electricity at an efficiency of 39%, burning 10,000 Btu/lb coal. The vehicle emission factor for VOCs is 6 grams/mile; the coal-fired boiler emission factor for VOCs is 1.4 lb/ton coal; biogenic emission of VOCs is 0.4 kg/km²-hr on the average.

Every time fuel is burned, the carbon is converted to carbon dioxide (CO2), the natural end product of combustion. If we approximate the chemical formula for gasoline by the compound octane (C8H18) with a density of 739 grams/liter, the stoichiometric reaction for complete combustion is: C8H18 + 12.5O2 8CO2 + 9H2O Thus, for every mole of C8H18 fuel that is burned, eight moles of CO2 are produced, along with nine moles of water vapor. Estimate the CO2 emission in grams per mile for a car getting 12 km/liter of gasoline.arrow_forward
- Design a full-wave rectifier power supply using a 9.52:1 transformer. Assume that the outlet is120 V rms @ 60 Hz. Further assume that the diode turn-on voltage V D(on) is 0.7 V. Pick the valueof CL such that vo has a maximum ripple of 1 V p-p . Solve for the average value of vo = Vo (notethat this may be greater than 12 V) and iD(ave) = ID.arrow_forwardLight-emitting diodes (LEDs) are diodes made with III-V compound semiconductor materials such as aluminum gallium arsenide (AlGaAs), aluminum indium gallium phosphide (AlInGaP) or indium gallium nitride (InGaN), instead of silicon. The LEDs emit light when the device is operated under forward bias. LEDs of different colors have different turn-on voltages VD(on). For example: VD(on) : Red: ~ 1.6 V Yellow: ~ 1.7 V Green: ~ 1.8 V Blue: ~ 2.8 V White: ~ 3.8 V (a) Model these five LEDs with a simplified piecewise linear model (b) A rule of thumb is that it takes about 1 mA of current to “light” an LED while ~ 10 mA is needed for it to appear bright. Use the piecewise linear model for the LEDs, for the over-voltage indicator circuit to the right, find the values of Vin which will cause D1 or D2 to light (i.e. when ID1 or ID2 exceeds 1 mA).arrow_forwardThe farming plan of steel structure has 30 ft long simply supported beams spaced at 8 ft apart.
