COMPLETE SOLUTION. FINAL ANSWER ARE IN ENGLISG SYSTEMS. DRAW A DIAGRAM IF NECESSARY. An experimental UAV (or Unmanned Aerial Vehicle) is to be equipped with two engines with ideal cycle efficiency of 65% and 95%. The engine follows the fundamental principles/ concepts of cyclic processes. Each engine is to be rated with 1150 Watts-hour of work developed. Determine (a) the heat supplied, (b) the ratio of heat supplied to heat rejected, and (c) the ratio of work developed to heat rejected on each engine.
As shown in the figure below, two reversible cycles arranged in series each produce the same net work, Weycle. The first cycle receives energy QH by heat transfer from a hot reservoir at TH = 1500°R and rejects energy Q by heat transfer to a reservoir at an intermediate temperature, T. The second cycle receives energy Q by heat transfer from the reservoir at temperature T and rejects energy Qc by heat transfer to a reservoir at Tc = 500°R. All energy transfers are positive in the directions of the arrows. Hot reservoir at T RI W. cycle Reservoir at T R2 Wcycle Cold reservoir at Te Determine: (a) the intermediate temperature T, in °R, and the thermal efficiency for each of the two power cycles. (b) the thermal efficiency of a single reversible power cycle operating between hot and cold reservoirs at 1500°R and 500°R, respectively. Also, determine the ratio of the net work developed by the single cycle to the net work developed by each of the two cycles, Woycle-
Water is the working fluid in a reheat-regenerative Rankine cycle with one closed feedwater heater and one open feedwater heater. Steam enters the turbine at 1400 lbf/in.² and 1100°F and expands to 500 lbf/in.2, where some of the steam is extracted and diverted to the closed feedwater heater. Condensate exiting the closed feedwater heater as saturated liquid at 500 lbf/in.² undergoes a throttling process to 120 lbf/in.² as it passes through a trap into the open feedwater heater. The feedwater leaves the closed feedwater heater at 1400 lbf/in.² and a temperature equal to the saturation temperature at 500 lbf/in.² The remaining steam is reheated to 1000°F before entering the second-stage turbine, where it expands to 120 lbf/in.² Some of the steam is extracted and diverted to the open feedwater heater operating at 120 lbf/in.2 Saturated liquid exits the open feedwater heater at 120 lbf/in.² The remaining steam expands through the third-stage turbine to the condenser pressure of 2 lbf/in.²…

Perform a parametric study for a steam power plant operating between pressures of 7 MPa and 7 kPa on an ideal Rankine cycle. Use feedwater heater pressure as the variable. Produce plots similar to Figure IIb.2.3 for such parameters as fraction of the steam extraction, pump work, and turbine work.
Problem 1 (10 pts) (a) A heat engine operates between a reservoir at 350°C, from which it absorbs 200 kJ of heat per cycle, and a reservoir at 0°C, to which it rejects 115 kJ of heat per cycle. Determine if this engine represents a reversible, irreversible, or impossible cycle? (4 pts)
Determine the specific work output, specific fuel consumption and thermal efficiency of a gas turbine power plant which produce a power output of 20 MW. The pressure ratio across the compressor is 4. Hot gases enters the turbine at 1100 K, the isentropic efficiencies of the compressor and turbine are 85% and 87% respectively. Pressure losses across the combustion chamber, heat exchanger air- side and heat exchanger gas-side are 0.08bar, 0.12bar and 0.04 bar respectively. The used fuel of LCV= 44000 kJ/kg, the heat exchanger effectiveness of 80%, ambient conditions are 1.0 bar and 288 K. Air/fuel ratio is 50:1 . Note for air γ= 1.4 and CP = 1.005 kJ/kg.K for hot gases γ= 1.33 and CP = 1.135 kJ/kg.K
a) An engineer proposed a design of cyclical engine that operates at the energy source whose temperature is 550 K and a sink at 300 K that generates waste heat. In the design proposal, it has been claimed that the cyclical engine can produces 5 kW while rejecting heat at a rate of 15000 kJ/h. Evaluate if the design proposal is valid.
