Assume that a recently commissioned generating station in Oman has an overall efficiency of 15% and 0.75kg of coal is burnt per kwh by the station. Evaluate the energy value of coal? Set up a new power plant in Ibri, which has three generators. One generator is coupled to turbine which is driven by energy from natural gas and the other two generators are coupled to turbines which are driven by energy from steam, how will you connect this power plant to a 220KV grid? Enumerate its operation with suitable schematic

In a gas turbine generating station the overall compression ratio is 12/1, performed in three stages with pressure ratios of 2.5/1, 2.4/1, and 2/1 respectively. The air inlet temperature to the plant is 25 ℃ and intercooling between the stages reduces the temperature to 40 ℃. The HP turbine drives the HP and intermediate-pressure compressor stages; the LP turbine drives the LP compressor and the generator. The gases leaving the LP turbine passed through the heat exchanger which heats the...

A nuclear power plant has an overall efficiency of 31% and a power output of 800MW. For one year operating at full capacity, calculate a) the number of joules produced; b) the number of fission events that were required to produce those joules; c) the mass of uranium oxide (UO2) that has been used in fission; and d) the market cost of that uranium oxide if it was all high quality.

An energy company has recently enhanced its capabilities for generating electricity, resulting in a 10% reduction in the cost/kwh. The company, which is regulated by the state, is required to pass the savings on to consumers via a 10% reduction in rates/kwh. Assume that the company has 100,000 residential customers who paid an average of $60/month consuming each 500 kwh/month in the year prior to implementing the new system; the same 100,000 customers paid $58/month following the shift to the...
