What else can I help you with?
Can Bernoullis equation describe the flow of water that is cascading down a rock-strewn spillway Explain?
You cannot use Bernoulli's equation because the rocks would create a turbulent flow and you need a steady flow to use Bernoulli's equation. It could (in theory) but you would need accurate measurements of size shape and placement of each of the rocks involved. It would be a nightmare just to accumulate the data.
Is Bernoulli equation applicable for unsteady flow?
The equation assumes steady state or laminar flow and hence cannot be used for turbulent flows.
What is the rate of water flow through a 100mm diameter pipe with 300mm head pressure?
300mm is a very low head, you can't expect much flow through that pipe, but you can work it out from the mechanical energy balance equation.
Why poiseuille equation not applied to turbulent flow?
Coz poiseuille eq is for poiseuille flow, which is a laminar flow, not turbulent flow. And it also need to be a fully developed , pressure driven flow.
What is the effect of resistance of the flow of current?
Thet resistor opposes the flow of current through it becoz of its internal construction. Its material has opposing property.
What is the equation for fluid flow?
is the equation for flow velocity
How does construction affect water?
Construction can affect water quality by causing erosion, sediment runoff, and pollution from construction materials. It can also disrupt natural water flow patterns, leading to changes in aquatic habitats and ecosystems. Additionally, construction activities can deplete or contaminate local water sources, impacting both human and aquatic life.
What are the disadvantages of flat roof construction?
Flat roof construction has many disadvantages. However the main disadvantage is that there is nowhere for rainfall water to flow. It will settle on the roof causing dampness.
What is the purpose of using a drain sock in a construction project?
A drain sock is used in construction projects to prevent sediment and debris from clogging the drain system, allowing water to flow freely and reducing the risk of flooding or water damage.
How does construction affect the hydrosphere?
Construction can impact the hydrosphere by altering the natural flow of water, leading to increased runoff and potential erosion. Construction activities can also introduce pollutants like sediment, chemicals, and debris into nearby water bodies, affecting water quality and aquatic ecosystems. Additionally, changes in land use due to construction can disrupt the hydrological cycle and exacerbate flooding or drought in an area.

What is the relationship between pressure and flow rate in a system, as described by the pressure vs flow rate equation?
In a system, the relationship between pressure and flow rate is described by the pressure vs flow rate equation. This equation shows that as pressure increases, flow rate decreases, and vice versa. This means that there is an inverse relationship between pressure and flow rate in a system.
Is Bernoulli equation applicable for unsteady flow?
The equation assumes steady state or laminar flow and hence cannot be used for turbulent flows.
Do water resivores leak?
Depending on the construction of the reservoir, yes it can leak. Especially if shaped explosives are used at key flow points in the structure.
How are the continuity equation and bernoulli's equation related?
Continuity equations describe the movement of constant. Bernoulli's equation also relates to movement, the flow of liquids. For some situations, where the liquid flowing is a constant, both a continuity equation and Bernoulli's equation can be applied.
Why you use partial differential equation?
PDEs are used in simulation of real life models like heat flow equation is used for the analysis of temperature distribution in a body, the wave equation for the motion of a waveforms, the flow equation for the fluid flow and Laplace’s equation for an electrostatic potential.
Heat gain due to friction in water flow?
Frictional heat gain in water flow is the result of mechanical energy being converted into thermal energy as water moves past surfaces and obstacles, causing molecules to rub against each other and generate heat. It is influenced by factors such as flow velocity, pipe roughness, and viscosity of the fluid. This heat generation can be calculated using formulas like the Darcy-Weisbach equation or the Colebrook-White equation.
