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 […]
Can you use microwave with generator?
Can you use microwave with generator? When experiencing a power outage, you can use a gas-powered generator to run various electrical appliances, including a microwave oven. Before attempting to connect the microwave to your generator, you must make sure to size the generator properly, otherwise the microwave will not operate at its full capacity. How […]

What kind of microscope would be used to study a while or opaque object?
What kind of microscope would be used to study a while or opaque object? The stereo microscope, also called a dissecting microscope, provides magnification of up to 300 times. These binocular microscopes are used to look at opaque objects or objects that are too large to be viewed with a compound microscope, since they do […]
What is the principle of nuclear magnetic resonance imaging?
What is the principle of nuclear magnetic resonance imaging? At resonance, the nuclear magnets tend to spin in phase with one another and a portion of the nuclear magnets are ele- vated to the excited state with their magnetic moments opposed to the applied magnetic field. In this example, a net magnetization is produced in […]
Why do mechanical and physical properties depend on the density of PM parts?
Why do mechanical and physical properties depend on the density of PM parts? Explain why the mechanical and physical properties depend on their density. Mechanical properties rely on their density to maximize metal particle contact and cohesion which affects a metal’s strength, ductility, elastic modulus, and toughness. Describe the relative advantage of cold isostatic pressing. […]
Why is my computer always updating when I shut down?
Why is my computer always updating when I shut down? This could be because of your “Windows Update” settings. If it is configured to run frequently (daily), then the available updates downloaded in the temp location and will get installed when you shutting down your machine. What happens when you turn off your computer when […]
What problems may result by using an electrode at too low a current setting?
What problems may result by using an electrode at too low a current setting? What problems may result by using an electrode at too low a current setting? poor fusion and poor arc stability. Why is it usually better to make a weld in the flat position? This flat horizontal position allows for the maximum […]
What is the 90 90 rule?
What is the 90 90 rule? Knowledge at a glance: The 90-90 rule points out experiences in effort estimation, according to which 90% of work performed and an estimated 10% of remaining effort in practice become 180% (90%+90%). … What is a good rule of thumb for when to abstract code out into a separate […]
