An energy plant produces an output potential of 2100 kV and serves a city 238 km away. A high-voltage transmission line carries 580 A to the city. The effective resistance of a transmission line [wire(s)] is 1.83 Ω/km times the distance from the plant to the city. What is the potential provided to the city, i.e., at the end of the transmission line? Answer in units of kV. 005 (part 2 of 4) 10.0 points How much power is dissipated due to resistive losses in the transmission line? Answer in units of W. 006 (part 3 of 4) 10.0 points Assume the plant charges $ 0.097 /kW · hr for electric energy. At this rate, how much does it cost to transmit energy to the city (by the transmission line heating the atmosphere) each hour? Answer in units of dollars/hr. 007 (part 4 of 4) 10.0 points Consider the money lost by the transmission line heating the atmosphere each hour. Assume the energy plant produces the same amount of power; however, the output electric potential of the energy plant is 20% greater. How much money per hour is saved by increasing the electric potential of the power plant? Answer in units of dollars/hr.

An energy plant produces an output potential of 2700 kV and serves a city 202 km away. A high-voltage transmission line carries 460 A to the city. The effective resistance of a transmission line [wire(s)] is 1.69 Ω/km times the distance from the plant to the city. 1) Assume the plant charges $ 0.105 /kW · hr for electric energy. At this rate, how much does it cost to transmit energy to the city (by the transmission line heating the...

A wastewater treatment plant serves 5,000,000 people. Each person on the average produces 0.1m^3 per person per day of wastewater. If the ultimate BOD of the discharge from the plant is 50 mg/L into a 5-meter deep stream that has an average flow rate of 10m^3 per second, a velocity of 1 meter per second, and a BOD value of 5 mg/L. The deoxygenation constant Kd is 0.19/day, and DO at the mix point is 8.5 mg/L. The water temperature...

A bicycle manufacturer currently produces 369,000 units a year and expects output levels to remain steady in the future. It buys chains from an outside supplier at a price of $1.90 a chain. The plant manager believes that it would be cheaper to make these

A bicycle manufacturer currently produces 369,000 units a year and expects output levels to remain steady in the future. It buys chains from an outside supplier at a price of $1.90 a chain. The plant manager believes that it would be cheaper to make these chains rather than buy them. Direct in-house production costs are estimated to be only $1.60 per chain. The necessary machinery would cost $293,000 and would be obsolete after ten years. This investment could be depreciated to...
