Rene70% alcohol is commonly used for sterilization as it is more effective at killing bacteria and viruses compared to higher concentrations of alcohol. The 70% concentration allows for better penetration into microbial cells, leading to better disinfection. It also evaporates more slowly, providing more contact time for effective sterilization.

What is a laminar cloud?
A laminar cloud is a type of cloud that appears in long, parallel bands with smooth, regular edges. These clouds are associated with stable atmospheric conditions and are often seen in the form of altocumulus or cirrocumulus clouds. They usually indicate fair weather.
Why you determine reynold number in fluid mechanics?
The Reynolds number is a dimensionless quantity used in fluid mechanics to predict the flow regime in a system. It helps determine whether the flow is laminar or turbulent. This is important for understanding the behavior of fluids in different scenarios, such as in pipes, around objects, or in boundary layers.
What is vermiculite made out of?
Vermiculite is a naturally occurring mineral that expands when heated. It is composed of a group of hydrated laminar minerals. When heated, it expands to create lightweight, fire-resistant, and absorbent material commonly used in gardening, insulation, and construction.
What are the applications of circular orifice?
Circular orifices are commonly used in flow measurement devices such as orifice plates, venturis, and nozzles. They are also used in pressure relief valves, regulators, and in various industrial processes for controlling or monitoring flow rates of liquids or gases. Additionally, circular orifices can be used in hydraulic systems for controlling fluid flow and creating pressure differentials.
Is hydrogen more flammable than petrol?
Yes, hydrogen is more flammable than petrol. Hydrogen is a highly flammable gas that can ignite easily and burn with a colorless flame, making it a potential fire hazard. Additionally, hydrogen has a wider flammability range compared to petrol, meaning it can ignite at lower concentrations in the air.
