Select a developing region of the world with limited electrical power. Recommend a source of energy (i.e. Qdot in) for the electric generation appropriate for the region and propose a power plant configuration operating on the superheated Rankine cycle to meet the anticipated power need. Include a thermodynamic analysis of the cycle and estimate the power output from the cycle and the annual revenue generated from the sale of electricity. Summarize your design, and discuss the assumptions you make. Estimate...

A local coal fired 200 megawatt electrical generating plant has a thermal efficiency of 30% and a nuclear 150 megawatt electrical generating plant has a thermal efficiency of 25%. a. Calculate the waste heat emitted by each (in megawatts) b. If the cooling water used for the nuclear plant were required to only rise in temperature by 2o C after it absorbs the waste heat, how much water per hour would be required to cool the nuclear plant (in cubic...

Steam power plants are responsible for the production of most electric power in the world. A small increase in thermal efficiency can mean large savings from the fuel requirements. Consider a steam power plant that operates on a simple ideal Rankine cycle. Steam is cooled in the condenser at a pressure of 75 kPa by running cooling water at 16°C from the nearby river through the tubes of the condenser. To increase the thermal efficiency of the power cycle, a...

Current Designs is always working to identify ways to increase efficiency while becoming more environmentally conscious. During a recent brainstorming session, one employee suggested to Diane that the company should consider replacing the current rotomold over as a way to realize savings from reduced energy consumption. The oven operates on natural gas, using 30600 therms of natural gas for an entire year. A new energy efficient rotomold oven would operation on 2700 therms of natural gas for an entire year....

Fuel selection for electricity generation 1. Uncontrolled emission factors and heating value data for bituminous coal, residual fuel oil and natural gas burned in utility boilers are given in Table 1. Consider a thermal electric power plant that generates an average of 400 MW of electricity with an overall efficiency of 35%. Determine for each fuel the annual uncontrolled mass of each of the pollutants (in units of metric tonnes per year) that would be emitted from such a power...

Davis Industries must choose between a gas-powered and an electric-powered forklift truck for moving materials in its factory. Because both forklifts perform the same function, the firm will choose only one. (They are mutually exclusive investments.) The electric-powered truck will cost more, but it will be less expensive to operate; it will cost $22,000, whereas the gas-powered truck will cost $17,500. The cost of capital that applies to both investments is 12%. The life for both types of truck is...
