How might these responsibilities be fulfilled simultaneously? (Hint: Evaluate the engineering responsibility to public safety and environment in the development of new power plant)
Concentrating solar collectors are used to provide the heat source for a Rankine cycle using water as the working substance. The design specifications require a power output of 10 MW. Commercially available collectors allow steam to be generated at 2500 kPa and 3200C. The cycle low pressure is assumed to be 8 kPa. Determine (a) the cycle thermal efficiency; (b) the mass flow rate of steam; and (c) the mass flow of cooling water if its temperature increases by 12oC.
Represent the Carnot cycle as a square on the T-S plane. Now inscribe within the square of a circle of maximum diameter D which represents a cycle. Noting that both cycles operate between the same temperature limits T1 (source) and T2 (sink), demonstrate that the Carnot cycle is the more efficient.
Pls answer thank you! The following data were obtained during performance test with a simple open cycle gas turbine engine: compressor inlet temperature, 520*R: compressor isentropic discharge temperature, 672"R: actual compressor discharge temperature, 691"R: turbine inlet temperature, 1500 R: turbine isentropic discharge temperature. 1184"R: and turbine actual discharge temperature, 1216°R. For these conditions calculate the thermal efficiency in percent.
