Impulse turbines have the advantage of operating efficiently with high-pressure water, making them suitable for high-head applications. They can handle variations in water flow and pressure without significant performance loss, as they rely on the momentum of water jets rather than pressure differences. Additionally, impulse turbines typically have simpler designs and are easier to maintain compared to reaction turbines, which require more complex components to manage pressure changes.

What is impulse and reaction blades?
Impulse and reaction blades are two types of turbine blade designs used in steam and gas turbines. Impulse blades convert the thermal energy of steam or gas into mechanical energy by directing the flow onto the blades, causing them to spin. Reaction blades, on the other hand, create lift through the pressure difference generated by the fluid flow over their shape, relying on both the pressure and the velocity of the fluid. Together, these blade types optimize turbine efficiency and performance in energy conversion applications.
What does steam do to a turbine?
Steam (under pressure) comes into contact with the blades of the turbine through which it is flowing and, by the direct application of force, causes the blades to move, turning the turbine shaft. The turbine coverts the thermal energy of the steam into (rotating) mechanical energy. Surf on over to our friends at Wikipedia using the provided link and get more info. Oh, and check out the pics! Answer it depends what type of turbine one is using types of steam turbine 1 impulse turbine 2 reaction turbine in 1 st one steam is completely expanded inside nozzle and all pressure energy get converted in to kinetic energy using this impulse force turbine runs. in 2nd steam is multiple stage blades are used where high pressure superheated steam gets expanded inside the turbine in each stage and after each stage velocity of steam increases. very high temperature superheated steam is reaquired because it has very high specific volume which helps in reducing mass flow rate of steam.
How is impulse related to force?
Impulse is the product of force and the time over which the force is applied. Therefore, impulse is directly related to force, as a larger force applied over a longer time will result in a greater impulse. Mathematically, impulse is equal to the force multiplied by the change in time.
Where does an impulse move from on neuron to the other?
The impulse has to cross over a synapse to another neuron or an effector.
Does impulse equal to momentum?
No, impulse is the change in momentum of an object over a certain time interval. Momentum is a measure of how difficult it is to stop an object's motion, while impulse is the force applied to an object over time. So, impulse and momentum are related but not equal.
What force applied over a period of time is called?
Force applied over a period of time has the dimensions of momentum, and is referred to as "impulse".
What is the intensity of an impulse determined by?
The intensity of an impulse is determined by the product of its magnitude and the duration of time over which it acts. In physics, impulse is defined as the change in momentum of an object, which can be quantified as the integral of force over time. Therefore, a stronger force applied over a longer period results in a greater impulse. Additionally, the impulse's effects can be influenced by the mass and initial velocity of the object involved.
What is the impulse of a force of 10N exerted over 5s?
The impulse of a force is the product of the force and the time it is applied. In this case, the impulse is 10N * 5s = 50Ns.
How do you you calculate impulse?
Impulse is calculated by multiplying the force applied to an object by the time interval over which the force is applied. The equation for impulse is J = F * Δt, where J is the impulse, F is the force, and Δt is the time interval.
What is the difference between an impulse and step responses?
An impulse response describes the system's output when an impulse is applied as input, showing the system's reaction over time. A step response, on the other hand, shows the system's output when a step function is applied as input, indicating how the system behaves when experiencing a sudden change in input signal.
What is a good sentence for the word impulse?
Her impulse to shop was starting to take over her whole life. Another good sentence would be, she had a sudden impulse to buy the expensive purse.
What is Converging Circuit?
a neural curcuit in which a single impulse is transmitted over and over is a?
