Steam is generated at 4.10 Mpa and 440°C and condensation occurs at 0.105 MPa a. For a Rankine engine operating between these limits, computethe thermal efficiency and the heat rate b. Considering that a Rankine cycle occurs between same limits, determine QA, QR, Wnet and eth c. What mass flow rate is required for a net output of 30 000 kW   Don't answer the given problem, just give me the schematic diagram and t-s diagram of the given problem

In a cyclic comprising of air compressor and expansion, workdone by a prism during the compression stroke is 9.2KJ and the heat rejected to the surrounding is 50KJ. During the expansion stroke workdone by air on the prism is 8.4KJ. a) Determine the quality of heat transferred to or from the system. Tullow oil has discovered a large volume of crude deposit at Cape-3-Point along the western coast of Ghana after years of intensive exploration. In the Company’s bid to start exploration, Green Ghana an environmental protection NGO took Tullow to court to prevent the Company from embarking on the said project citing numerous environmental concerns. b) As an energy and sustainability expert, what do you think are the side effects of the project and their remedies? A cooling water pump is operating at a speed of 1800rpm. Its flow rate is 1800L/minutes at a head of 14.4m and the power of the pump is 45kw. c) Determine the power required if the pump speed is increased…

If the Rankine cycle shown in the figure is an "Ideal Rankine cycle", what assumptions do you typically make? Select all that apply: Turbine Boiler Condenser - Qout (KL: 45 sec) (Chien-Ming: 1 min) RR: up to 1min NT = 100% O Wr > Wp O State 4 is a saturated liquid O X3 = 1

A four-cylinder spark-ignition engine with a compression ratio of 8 has a pistonswith a bore of 9 cm and a stroke of 10 cm. The air pressure at the beginning of thecompression is 98 kPa, and the temperature is 37 oC. The engine may be modeled by theair-standard Otto cycle. The maximum cycle temperature is 1700 oK. If the engineproduces 75 kW of power, determine a) the heat supplied per cylinder; b) the thermalefficiency; and c) the rpm required.

Prob-2 In a Rankine cycle steam power plant 0.9 MW energy is taken out in the condenser, 0.63 MW power is taken out in the turbine, and the pump work is 0.03 MW. (a) Find the plant thermal efficiency. (b) if cycle is reversed, consider turbine is a compressor; condenser is an evaporator; find the COP of the air-conditioning system. QH QL WI
