How is the heat added in the Otto cycle?

How is the heat added in the Otto cycle? Through the combustion of fuel, heat is added in a constant volume (isochoric process) process, followed by an adiabatic expansion process power (C) stroke. The cycle is closed by the exhaust (D) stroke, characterized by isochoric cooling and isobaric compression processes. In which of the following […]

What is stationary refrigeration?

What is stationary refrigeration? Refrigerant emitted during the normal operation of air-conditioning and refrigeration equipment (as opposed to during the maintenance, servicing, repair, or disposal of this equipment), such as from mechanical purging and leaks. … Is venting R134a illegal? R134a is not an ozone-destroying agent, but it is a greenhouse gas, and is illegal […]

What are the surface defects?

What are the surface defects? Surface defects are the boundaries, or planes, that separate a material into regions, each region having the same crystal structure but different orientations. What are the types of line defect? Point defects (vacancies, interstitial defects, substitution defects) Line defect (screw dislocation, edge dislocation) surface defects (material surface, grain boundaries) Substitutional […]

What is not true about machine learning?

What is not true about machine learning? Machine learning is artificial intelligence. Yet artificial intelligence is not machine learning. This is because machine learning is a subset of artificial intelligence. In addition to machine learning, artificial intelligence comprises such fields as computer vision, robotics, and expert systems. Which of the following is true about machine […]

What is the thermal efficiency of the cycle?

What is the thermal efficiency of the cycle? The thermal efficiency of modern steam turbine plants with reheat cycles can reach 47%, and in combined cycle plants, in which a steam turbine is powered by exhaust heat from a gas turbine, it can approach 60%. Which cycle has the highest thermal efficiency between two temperatures? […]

What is a thermally activated process?

What is a thermally activated process? A Thermally Activated Process is one in which the system must overcome an energy barrier in order for the process to go forward. The rate of these types of processes rises exponentially with temperature. What is recrystallization used for? Recrystallization is the most important method of purifying nonvolatile organic […]
