What is unit for flow rate for gases? Gas mass flow rate is the actual mass of a gas which moves through a measurement instrument per unit of time. Its units are usually in standard liters per minute (slpm) or standard cubic centimeters per minute (sccm) in SI units. The most common English units include […]
Can a bad fuel pump cause vapor lock?
Can a bad fuel pump cause vapor lock? Still, a modern fuel-injected system can suffer from vapor lock, not only if pressure in the fuel line drops (faulty fuel pressure regulator or fuel pump, for example) and the fuel line is subjected to high temperatures, but also modern engines that may reach between 248 and […]
What is the most important force driving erosion?
What is the most important force driving erosion? Water Erosion Water is the most important erosional agent and erodes most commonly as running water in streams. However, water in all its forms is erosional. Raindrops (especially in dry environments) create splash erosion that moves tiny particles of soil. What is the biggest driver for soil […]
What do the four elements symbolize?
What do the four elements symbolize? Ultimately what you manifest in the physical world can be attributed to a characteristic of earth, air, fire and water. Symbolically the four elements represent patterns of energy that transform life and by understanding their influences can be used as a tool for self-development. Whats is my soul? Your […]
Why do I feel sick during a storm?
Why do I feel sick during a storm? Approaching storms lower the air pressure. When atmospheric pressure decreases body tissues swell slightly. This can put increased pressure on joints and sinuses. Low temperatures also causes blood viscosity, or thickness. Does thunder affect mood? Thunderstorms are dramatic events, so it’s not surprising that they often bring […]
Why is shale gas bad?
Why is shale gas bad? But US researchers found that shale gas wells leak substantial amounts of methane, a potent greenhouse gas. This makes its climate impact worse than conventional gas, they say – and probably worse than coal as well. Is shale gas a renewable resource? Shale gas is non-renewable, and also polluting but […]
At what point is acceleration the greatest?
At what point is acceleration the greatest? Neglecting air resistance for the moment, the remaining force is that of gravity which is always g and directed downward. So the acceleration at the highest point is the same as at launch time, i.e. -9.8 meters/sec2 in the vertical direction. What is the acceleration just before it […]
What are the three basic types of bridges?
What are the three basic types of bridges? Bridges can be found in a variety of shapes, but 3 basic designs rule the day; beam, arch, and suspension. What are the main parts of a bridge? The main components of a bridge are the foundation, substructure, and the superstructure. Each of these core areas have […]
Is a change of temperature a chemical reaction?
Is a change of temperature a chemical reaction? A change in temperature is characteristic of a chemical change. If temperature increases, as it does in most reactions, a chemical change is likely to be occurring. This is different from the physical temperature change. During a physical temperature change, one substance, such as water is being […]
How do neutrons kill?
How do neutrons kill? Since neutrons are scattered and absorbed by air, neutron radiation effects drop off rapidly with distance in air. The intense pulse of high-energy neutrons generated by a neutron bomb is the principal killing mechanism, not the fallout, heat or blast. Does a neutron bomb exist? A neutron bomb is actually a […]
