IMPORTANT: For problem solving items, start your solution by presenting the cycle in P-v and T-s diagrams. Label all points and mark the process where the heat is added and rejected. Also mark the area showing the net work of the cycle. The parameters of the initial state of one kilogram of air in the cycle of an internal combustion engine are o.095 MPa and 65 deg.C. The compression ratio is 12. Compare the values of the thermal efficiency for isobaric and isometric heat supply in the amounts of 820 kJ.

Consider a regenerative vapor power cycle with a single open feedwater heater. Steam enters the first turbine stage at 12MPa, 500 0C, and expands to 0.3MPa where some steam is extracted and fed to the feedwater heater. The remainder expands through the second-stage turbine and exits at the condenser pressure of 0.01 MPa. Saturated liquid at 0.3 MPa leaves the open feedwater heater. If the net power output of the cycle is 100 MW,and the turbine stages and pumps are isentropic, determine (a) the thermal efficiency, and(b) the mass flow rate of steam entering the first turbine, in kg/h.

PLEASE FOLLOW THE INSTRUCTION.
A power plant operates in an idealized Rankine cycle, using water as the working fluid (Figure 3). The steam at the exit of the boiler has a pressure of 6 MPa and temperature of 600 °C (point 1). The water at the exit of the condenser has a pressure of 15 kPa (point 3). The condenser employs a nearby river as the cooling source, which can be regarded to have a constant temperature of 25 °C. The mass flow rate of the steam is 80 kg/s. The hot reservoir has a temperature of 1400 K. Regard water as an incompressible liquid. During pumping, the density of water remains unchanged as Point 3 in Figure 3. Qin Boiler i wwwwww Pump Turbine Wp 3 Figure 3 W₁ Cooling water Condenser
Steam is supplied to a two-stage turbine at 40 bar and 350°C. It expands in the first turbine until it is just dry saturated, then it is re-heated to 350°C and expanded through the second-stage turbine. The condenser pressure is 0.035 bar. Calculate the work output and the heat supplied per kilogram of steam for the plant, assuming ideal processes and neglecting the feed-pump term. Calculate also the specific steam consumption and the cycle efficiency

104#1. an ideal gas with R=0.062 BTU/lbm-degree R and Cv=0.158 BTU/lbm-degree R undergoes athree process cycle in a cklose system. from the initial state of 20 psia and 570degree R, the gas is compressed at coinstant pressure to 1/5 of its initial volume, process 1-2; it is then heated isochrocally to state 3, process 2-3; and finally, it expands polytopically with index n=1.5 back to its initial state, process 3-1. determine the pressure, specific volumes and temperatures at cardinal points around the cycle and the cycle thermal efficiency.
Problem: The drawing (not to scale) shows the way in which the pressure and volume change for an ideal gas that is used as the working substance in a Carnot engine. The gas begins at point A (pressure = PA, volume = VA) and expands isothermally at temperature T until point B (pressure = PB, volume = V B) is reached. During this expansion, the input heat of magnitude Qn enters the gas from the hot reservoir of the engine. Then, from point B to point C (pressure Pc. volume = Vc), the gas expands adiabatically. Next, the gas is compressed isothermally at temperature T. from point C to point D (pressure = PD, volume = VD). During this compression, heat of magnitude Q. is rejected to the cold reservoir of the engine. Finally, the gas is compressed adiabatically from point D to point A, where the gas is back in its initial state. The overall process A to B to C to D to A is called a Carnot cycle. Prove The work done during the cycle equals the area enclosed by the path on the PV diagram. B…
