Question
Chapter 7, Problem 1RQ
To determine
The definition of service entrance.
Expert Solution & Answer
Explanation of Solution
The service entrance is one of the most crucial components of a residential electrical system. The service entrance gives the home's electrical system access to the electric utility company's power supply.
The service conductors at an underground service entrance run from the service main disconnect terminals to the point where the underground utility wire is connected.
Several of the requirements for the installation of service entrances are covered by Article 230 of the NEC®. The specifications for grounding a residential service entrance are covered by Article 250 of the NEC®.
The local electric utility must be approached after the kind of service entrance being placed is selected, and the service type, location, and installation must all be planned with them.
Conclusion:
The service entrance gives the home's electrical system access to the electric utility company's power supply.

For automobile, gasoline is a complex mixture of relatively volatile hydrocarbon blended for use in spark-ignition engines. Every time fuel is burned, the carbon is converted to carbon dioxide (CO2), the natural end product of combustion. If we approximate the chemical ormula 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, alon with nine moles of water vapor. Estimate the CO2 emission in grams per mile for a car getting 12 km/liter of gasoline.
An urban county with an area of 1,000 mile2 has an estimated 18 million miles of vehicular traffic per day and has a large power plant. 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. Determine the total emissions of VOCs in tons/day from all sources (mobile, power plant, and biogenic).
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.arrow_forwardAn 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.
