Empirical equations used in a turbulent flow system?
there are many empirical constellations in turbulent flow depending upon the conditions like whether flow is internal or external, flow over a flat plate of pipe etc. so its better to refer a book on fluid mechanics.
What is turbulent viscocity?
Turbulent viscosity is a value which is assumed to be equal in all directions. It is the same as Eddy Viscosity This is a measure of a fluid which is being deformed by stress. The fact that it is turbulent just means it is changing so the internal friction or viscosity is changing constantly and this is why it is called turbulent. the internal friction is the friction within the object hence the term internal however this friction derives from the force of the fluid acting on the object. E.G if air is your fluid surrounding the object and the object is experiencing a change in the velocity of the air it will be exposed to a different amount of stress and will therefore have a different value for internal friction.
What is the difference between hydraulic motors and pumps?
A hydraulic pump uses an external mechanical force to pressurize the hydraulic fluid. A hydraulic motor uses the pressurized hydraulic fluid to apply a mechanical force an external machine. See the difference between a pump and a motor.
Capacity of pipe?
In order to calculate the internal capacity of a pipe use the formula pi x internal radius x internal radius x length of pipe where pi = 3. 142. This is the volume of a cylinder; pipe capacity is usually amount of flow per unit of time under given conditions of internal roughness, and viscosity of the flowing fluid with a given pressure loss per length unit
What are some similarirtes between hydraulic and pneumatic systems?
They are both pressurized fluid systems. They both use pumps to pressurize the fluid. They both use piping to contain the fluid, and they both drive motors and cylinders.
What is the fluid link between the external and internal environment?
The fluid link between the external and internal environment is the plasma membrane of cells. It acts as a selectively permeable barrier that regulates the passage of substances in and out of the cell, maintaining the cell's internal environment while interacting with the external environment.
Is pressure internal or external?
Pressure can be both internal and external. Internal pressure refers to the force exerted by a fluid within a closed system, while external pressure can be the force exerted by a substance or object outside of the system onto the system.
What is the difference between internal and external flow?
About of Blood's flow:A fluid flow is classified as being internal or external, depending on whether the fluid is forced to flow in a confined channel or over a surface. The flow of an unbounded fluid over a surface such as a plate, a wire, or a pipe is external flow. The flow in a pipe or duct is internal flow if the fluid is completely bounded by solid surfaces. The flow of liquids in a duct is called open-channel flow if the duct is only partially filled with the liquid and there is an free surface, e.g. the flows of water in rivers and irrigation ditches.
What reduces the friction between the parietal and visceral surfaces of an internal cavity is the function of?
The function of serous fluid reduces friction between the parietal and visceral surfaces of an internal cavity. Serous fluid is a lubricating fluid secreted by serous membranes that helps organs move smoothly within body cavities.
What is the difference between compressible and in-compressible fluids giving examples of the fluids found in human body?
compressible fluid changes its volume when external pressure is applied and in-compressible fluid does not change its volume due to external pressure
Why do I Have to rev car to get into gear?
Low transmission fluid, or an internal trasnmission failure.Low transmission fluid, or an internal trasnmission failure.
What cavity contains organs that maintain homeostasis when the body is exposed to internal and external stimuli?
The abdominal cavity contains organs such as the kidneys, liver, and intestines that help maintain homeostasis in response to internal and external stimuli. These organs regulate functions such as temperature, fluid balance, and metabolism to keep the body in a stable state.
How does an external combustion engine work?
An external combustion engine (EC engine) is a heat engine where an fuel is burned outside the engine, which heats an internal working fluid. The fluid expands and drives the engine to produce motion or usable work. Conversely, internal combustion engines burn or explode the fuel within the engine, using the expanding exhaust gases to do work. Examples of external combustion engines are coal and oil-fired boilers on ships and in locomotives, and the "Stanley Steamer, " an early steam-powered motorcar.
What is gear oil pump?
A gear pump uses the meshing of gears to pump fluid by displacement.[1] They are one of the most common types of pumps for hydraulic fluid power applications. Gear pumps are also widely used in chemical installations to pump fluid with a certain viscosity. There are two main variations; external gear pumps which use two external spur gears, and internal gear pumps which use an external and an internal spur gear. Gear pumps are positive displacement (or fixed displacement), meaning they pump a constant amount of fluid for each revolution. Some gear pumps are designed to function as either amotor or a pump.
What is the difference between internal and external transmission oil coolers?
An internal cooler is a small internal radiator inside the lower end of a regular radiator. It has two lines running to it from the transmission. This internal radiator gets cooling from the "coolant" that flows through the radiator regularly during running of the vehicle. The reason it is at the bottom of the rad (usually a veritcal flow type) is that the hot coolant comes into the rad at the top and then is cooled as it falls to the bottom. The smaller internal rad is also cooled by this "cooler" coolant (antifreeze and water mixture) and thusly cools the hot transmission fluid. This internal rad is separate from the regular cooling system and is a "closed System" within a system. An EXTERNAL transmission cooler is a small rad that is used exclusively for cooling of the automatic transmission fluid. It is completely separate from the rad but many times is mounted in front of the radiator. External coolers have much more volumetric efficiency and can handle larger quantities of fluid. They are installed on anything that may have a trailer towing package. Automatic transmissions get very hot while towing and need the extra cooling if they are pulling a load.
When the speed of a fluid flowing in a horizontal pipe increases what happens to the internal pressure?
Due to friction between the fluid and the walls of the pipe, pressure increases within the pipe.
