A power plant taps steam superheated by geothermal energy to 421 K (the temperature of the hot reservoir) and uses the steam to do work in turning the turbine of an electric generator. The steam is then converted back into water in a condenser at 321 K (the temperature of the cold reservoir), after which the water is pumped back down into the earth where it is heated again. The output power (work per unit time) of the plant is...
QUESTION 1 A heat pump extracts heat from a cold temperature reservoir at 263 K at high temperature reservoir, an auditorium, at 298 K. The heat pump requires (a) Draw a schematic diagram of the heat pump a rate of Q, and rejects 8 kW of heat to a an input power of 2.5 kw system and the reservoirs and show all energies and their values and directions on the diagram. ing an energy balance on the system, determine the...
all six plz (better with explaination) 25. A real (non-Carnot) heat engine, opcrating between heat reservoirs at temperatures of 650 K (hot) and 270 K (cold) performs 4.3 kJ of net work and rejects 8.0 kJ of heat in a single cycle. The thermal efliciency of this heat engine is closest to A. 0.35. B. 0.31 C. 0.28 D. 0.38 E. 0.42 26. A 2.0-kg block of aluminum at 50° is dropped into 5.0 kg of water at 20°C and...
Using the book, write another paragraph or two: write 170 words: Q: Compare the assumptions of physician-centered and collaborative communication. How is the caregiver’s role different in each model? How is the patient’s role different? Answer: Physical-centered communication involves the specialists taking control of the conversation. They decide on the topics of discussion and when to end the process. The patient responds to the issues raised by the caregiver and acts accordingly. On the other hand, Collaborative communication involves a...
Please read the article and answer about questions. You and the Law Business and law are inseparable. For B-Money, the two predictably merged when he was negotiat- ing a deal for his tracks. At other times, the merger is unpredictable, like when your business faces an unexpected auto accident, product recall, or government regulation change. In either type of situation, when business owners know the law, they can better protect themselves and sometimes even avoid the problems completely. This chapter...
10. Write a one-page summary of the attached paper? INTRODUCTION Many problems can develop in activated sludge operation that adversely affect effluent quality with origins in the engineering, hydraulic and microbiological components of the process. The real "heart" of the activated sludge system is the development and maintenance of a mixed microbial culture (activated sludge) that treats wastewater and which can be managed. One definition of a wastewater treatment plant operator is a "bug farmer", one who controls the aeration...
