Fluid Dynamics

three types of combustion chamber are used in gas turbine engine

1) Can type.

1.1 single can ; this again can be of two type a) straight through design b)reverse flow design

1.2 multiple can

2) tubo-annular (can-annular)

3) annular

Intra-alveolar surface tension is due to the presence of surfactant molecules that reduce surface tension within the alveoli, preventing lung collapse by maintaining alveolar stability during breathing. Surfactant helps to reduce the work of breathing and facilitates gas exchange by preventing alveolar collapse at the end of expiration.

Intermediate interference refers to interference that occurs when a new memory interferes with the retrieval of an older memory, or when an older memory interferes with the retrieval of a more recent memory. This type of interference often occurs when similar information is involved, making it difficult to distinguish between the memories.

No, if the pressure difference results in a density change of less than thirty percent (30%) the fluid may be treated as incompressible by assuming the density of the fluid equals the average density and that the density is constant.

Water is effectively an incompressible substance, so pressure does not affect its' volume. However, its boiling and freezing points are directly related to the external pressure. Water boils when its vapor pressure is equal to the external pressure (or the atmospheric pressure if it is contained in some uncovered pot). Greater external pressure requires higher temperature for water so as to have that value of vapor pressure for it to boil. This is how pressure affects water.

Hence the diver must spin faster when moment of inertia become smaller to conserve angular momentum. In this way the diver can make more somersaults before entering the water.

The power required by a reciprocating pump is directly proportional to the discharge it produces. When the discharge increases, the power needed to maintain that flow rate also increases. This relationship is governed by the pump efficiency and the pressure head against which the pump is operating.

In fluid dynamics, a common example of using finite difference method is the discretization of the Navier-Stokes equations to solve for fluid flow equations. This entails approximating spatial derivatives with finite differences on a grid, which allows for numerical simulation of the fluid behavior in a computational domain.

Yes, when helium is in its superfluid state, it can conduct electricity with extremely low resistance due to its unique properties like zero viscosity and infinite thermal conductivity. This allows electricity to flow nearly friction-free, making it an ideal medium for certain applications like superconducting circuits and sensors.

A thermometer measures the amount of thermal energy a material has. This thermal energy is related to the vibrational and rotational energy the particles in the material have.

By using the thermometer to measure the temperature of a material you are, in effect, measuring the amount of energy the particles of that material have.

The height ( h ) of the object at time ( t ) can be modeled by the equation ( h(t) = -4.9t^2 + 5t ), where ( t ) is the time in seconds. This equation represents the object's height over time while it reaches its highest point at 2 meters after 0.5 seconds, then falls back down due to gravity.

The minimum volume of the ice slab would need to displace at least 45.0 kg of water to support the woman's weight without sinking. Given that freshwater has a density of approximately 1000 kg/m^3, the minimum volume can be calculated as 0.045 m^3 (45.0 kg / 1000 kg/m^3).

hair dryer, electrical energy enters the hair dryer and is converted to kinetic energy as a small motor spins a fan blade the electrical energy is converted to thermal by a grind of wires that heat up

A person who studies dynamics is typically called a "dynamics researcher" or a "dynamics scientist." Their specific area of study may be more specialized, such as a "mechanical engineer" if they focus on mechanical dynamics or a "fluid dynamics researcher" if they study the dynamics of fluids.

One example of an extrusion is the process of creating metal rails or bars by forcing raw metal through a shaped die to produce a continuous profile.

Motor oil heats faster than water, as water has one of the highest specific heat capacities. (It takes more energy to increase the temperature of 1 kg of water by 1 °C than to increase the temperature of 1 kg of oil by 1°C)

powder IS solid.

However, if you wanna make it into a larger chunk again, there are several ways. One is to melt it, then cool it, and you will have solid. However, you could dissolve it into other solutions, and then evaporate that solution, to form larger chunks, etc. =)

It is not so much the temperature of the water but the pressure that the hot water produces. If you will look at almost any car radiator cap you will notice a warning that says something to the effect
'warning contents under pressure. Do not remove when hot.'

Characteristics of an ideal gas:
- an extremely low concentration
- molecules are in a permanent motion
- Newton laws can be applied
- all collisions are elastic
- molecules are spherical
- molecules are not compressible

Air pressure decreases with increase of height.

Pump head decreases as volume flow rate increases due to the principle of conservation of energy. As the flow rate increases, the speed of the fluid also increases, resulting in higher kinetic energy. This leads to a drop in pressure and pump head as the energy is converted into kinetic energy instead of potential energy.

2.4 GPa is greater as giga is x10 to the power of 9 while mega is x10 to the power of 6.

2,400,000,000

or

27,600,000

i.e.

2.4 GPa = 2,400x106

2.76 MPa = 2.76x106

Pressure loss is typically larger in gas-liquid flow compared to liquid flow due to the compressibility of gas. Gas-liquid flow can experience significant pressure drops due to the expansion and compression of gas bubbles within the liquid, leading to greater friction losses.

Water evaporates faster at 100 degrees Celsius compared to 200 degrees Celsius because at 100 degrees Celsius, water reaches its boiling point and undergoes a phase change from liquid to gas. At 200 degrees Celsius, water is already in the vapor state, so there is no further evaporation taking place.
