Why Does entropy increase during a spontaneous process? If heat flows into the surroundings (i.e., when a reaction is exothermic) the random motions of the molecules in the surroundings increase. Thus, the entropy of the surroundings increases. The second law of thermodynamics states that the total entropy of the universe always increases for a spontaneous […]
What is a Class 3 thread?
What is a Class 3 thread? Class 3 threads are tight tolerance threads that have no allowance and have very tight tolerances. Class 3 threads are often specified for tight tolerance fastener applications in critical use situations where safety and strength are a primary concern, such as the aerospace industry. What are 3 types of […]
How do you calculate ice melting rate?
Is reliability a probability?
Is reliability a probability? Reliability is defined as the probability that an item will perform a required function without failure for a stated period of time. Another way to state is that It’s a measure of how long it takes for a network (or a system) to fail. So why Reliability is defined in terms […]
How does film boiling differ from nucleate boiling?
How does film boiling differ from nucleate boiling? Film boiling is a post critical heat flux (CHF) regime with a high surface temperature. Nucleate boiling is a type of boiling which occurs when the surface temperature is hotter than the saturated fluid temperature by a certain amount. In this type of boiling, the heat flux […]
Where do most pedestrian fatalities occur?
Where do most pedestrian fatalities occur? Most pedestrian deaths occur in urban areas, at non-intersection locations, and at night. Where do more than 50 percent of pedestrian motorist crashes occur? More than 50 percent of the combined total of fatal and injury crashes occur at or near intersections. In what situations are pedestrians most likely […]
What is a glass cullet?
What is a glass cullet? Crushed glass also known as glass cullet refers to waste glass produced as a result of breakage and rejection on quality control grounds during the manufacturing process. What is a Cullet? : broken or refuse glass usually added to new material to facilitate melting in making glass. What can be […]
What data should be encrypted during transmission through resort wireless networks to SBRU systems?
What data should be encrypted during transmission through resort wireless networks to SBRU systems? But, hotels may not be devoted to provide the security issues as SBRU. Therefore, the “personnel data”, “reservation information”, and “chat information” are encrypted during the transmission from resort to SBRU system and its local client software. For which subsystem S […]
What is the capacitive reactance of a 1 microfarad capacitor at 60 hertz?
What is the capacitive reactance of a 1 microfarad capacitor at 60 hertz? The capacitive reactance equals 1,000,000 divided by 6.28 times 60 hertz times 106.1 microfarads which equals 25 ohms. What is the reactance of a capacitor? Capacitive Reactance is the complex impedance of a capacitor who’s value changes with respect to the applied […]
