Which is a better disinfectant ethyl alcohol or isopropyl alcohol? Does alcohol kills germs and viruses? Isopropyl alcohol is effective against viruses such as FCV at 40% – 60% concentrations. Ethanol however, is more effective at 70% – 90% concentrations against FCV. Is ethyl rubbing alcohol the same as isopropyl alcohol? These two alcohols are […]
How is service factor calculated?
How is service factor calculated? Calculate or determine your service factor by choosing the service factor that corresponds to your hp and various RPM levels. For example, according to the table, if you have a 1HP motor and you operate it at 3600 RPM continuously, your service factor is 1.25. Multiply your motor horsepower by […]
Is the relationship between frequency and wavelength direct?
Is the relationship between frequency and wavelength direct? Wavelength (typically measured in nanometers) is the distance between two points in a wave. Frequency and wavelength have both direct and inverse relationships. The wave with shorter wavelength will have a higher frequency while a longer wavelength will have a lower frequency. Is frequency and energy directly […]
What happens when entropy decreases?
What happens when entropy decreases? The total entropy of a system either increases or remains constant in any process; it never decreases. For example, heat transfer cannot occur spontaneously from cold to hot, because entropy would decrease. Entropy is very different from energy. Entropy is not conserved but increases in all real processes. What causes […]

Which friction takes the most force to overcome?
Which friction takes the most force to overcome? sliding friction What are the 4 types of friction? Friction is the force that opposes motion between any surfaces that are in contact. There are four types of friction: static, sliding, rolling, and fluid friction. Static, sliding, and rolling friction occur between solid surfaces. What friction do […]
How much force is required to produce an acceleration?
What are 2 types of mixture?
What are 2 types of mixture? Types of Mixtures There are two main categories of mixtures: homogeneous mixtures and heterogeneous mixtures. What are the 5 examples of mixtures? Here are a few more examples: Smoke and fog (Smog) Dirt and water (Mud) Sand, water and gravel (Cement) Water and salt (Sea water) Potassium nitrate, sulfur, […]
What is a watershed explain?
What is a watershed explain? A watershed is an area of land that drains all the streams and rainfall to a common outlet such as the outflow of a reservoir, mouth of a bay, or any point along a stream channel. Why do we need watersheds? Watersheds are important because the surface water features and […]
