What is Flowing air responding to the difference between higher and lower pressure is responding to what?
pressure gradient
Why do rockets have a Diverging Nozzle at the exit?
To increase the exhaust velocity. +++ Pressure, not velocity. A gas flowing through a divergent nozzle gains pressure at the cost of speed.
What is the definition of velocity lag?
In a flow of matter, such as in a rocket, velocity lag is the speed difference between the flowing gas particles and solid/liquid particles. Any amount of velocity lag slows down the overall force and speed of the matter flow.
What happens to pressure and flow when a steadily flowing liquid flows from a small pipe to a large pipe?
you have a severe pressure drop and a loss of velocity
What is the difference between a gentle stream and a fast-flowing river?
A fast flowing river is faster
What is bernoulli's principle and its importance?
Bernoulli's Principle states that as the velocity of a fluid increases, the pressure of the fluid decreases. This is important in creating lift under an airplane's wing. Due to the shape of the wing, the velocity of the air (a fluid) flowing over the wing is higher, so the pressure over the wing is lower. The velocity of the air flowing under the wing is slower, so the pressure is higher. This creates lift which allows the airplane to take off and fly. Refer to the Related Links for an illustration.
The difference between charge and current?
Charge is potential, current is flowing.
What is the relation between velocity and flow rate?
Flow rate is volume of liqid flowing per unit time, velocity is displacement per unit time. For a constant cross-section area, the flow rate would increase with velocity and vice versa. This is because the volume flowing per unit time obviously increases if distance covered by the fluid increases. Picture a fluid flowing through a cylindrical pipe.
What is the flow in cubic feet per second in a ten inch diameter pipe flowing full with a flow velocity of 2.2 feet per second?
ZERO as there is NO pressure given
What is Gravity flow?
Gravity flow is fluid flowing due to the forces of gravity alone and not to an applied pressure head. In the Bernoulli equation, the pressure term is omitted, and the height and velocity terms are the only ones included.
Does the voltage moves?
Yes, voltage is a kind of electric pressure. It is also called potential. When there is potential difference between any two points, current starts flowing from high pressure point to low pressure point. FOR EXAMPLE : When there is a difference in air pressure between two regions, air moves from region of low pressure to region of high pressure causing winds In this case air is the potential and wind is electric current
What is difference between cavitation and supercavitation?
CAVITATION is the process of formation of vapour bubbles of flowing fluid in a region where the pressure of the liquid falls below its vapour pressure and the sudden collapsing of these vapour bubbles in region of high pressure. where SUPERCAVITATION IS THE CONTROLLED FORM OF CAVITATION WHICH HELP US TO attain more underwater speed
