Is the relation a function?
Not every relation is a function. But every function is a relation. Function is just a part of relation.
The function f(x) x3 is called the function?
The cubic function.
If an inverse function undoes the work of the original function what does the original function's becomes the inverse function's domain?
Range
How does the graph of the Mandelbrot set function relate to composite functions?
The Mandelbrot graph is generated iteratively and so is a function of a function of a function ... and in that sense it is a composite function.
What are the ways in describing a function?
A formula or graph are two ways to describe a math function. How a math function is described depends on the domain of the function or the complexity of the function.
What is penstock?

What is the giant tube in a hydropower plant?
penstock
What is a giant tube in a hydropower plant?
The giant tube in a hydropower plant is called Penstock. A Penstock is refers to the enclosed pipe that delivers water to the hydro turbines.
What is difference between penstock and pressure shaft?
Pressure Shaft is designed to resist Internal as well as External Pressure, but the Penstock is designed to resist Internal Pressure only. - Saravanan.S
Where surge shaft is located?
its connected at the start of penstock to reduce the "water hammering effect" in it.
How many penstocks supply water to the turbines?
ONLY 1 PENSTOCK that's all
Why forebay is used in hydroelectri power plant?
Head race tunnel are Non pressurized tunnels and Penstock is the tunnel bearing pressure. As there is the breakdown in the Power and the water is stopped entering through the turbines, the pressurized flow of water in the penstock creates hammer effect and goes back to the HRT. So, keeping Fore bay in between HRT and Penstock helps reducing pressurized water to create Water Hammers. Hence, to reduce the back water pressure effect, the Fore bay is used in the Hydro power Plant.
What is the difference between Headrace tunnel and Penstock in hydropower plants?
Pen stock is made of pipe while Tunnel is not a pipe.Tunnel is made of concrete material.
How do you calculate wall thickness of pen-stock pipe?
A penstock, with an internal diameter of 1.3 m, supplies water at a head equivalent to 127.6 kg/cm2. There is a possibility of 23per cent increase in the pressure due to transient conditions. The design stress and the efficiency of the joint may be assumed to be 1023 kg/cm2 and 35 per cent respectively.Calculate the approximate wall thickness of the penstock required
How is hydroelectric form?
Well, how was hydroelectricity formed. First of all people built dams in order to make a reservoir ( man made lake). All the water from the reservoir would then go down the penstock ( a water tube). The penstock would then lead into the turbine ( fan with spinning blades ) . Water would then strike the blade and cause the blade to rotate. The rotating motion would then cause electricity. The generator would guide the turbine through the way. The electricity would then get sent through the power lines.
How does the water turbine do what it does?
Water traels thru a pipe called a penstock then hits a turbine and the force makes the turbine spin. The energy created travels thru copper coil and goes to the generator. the water meanwhile goes to the river
Why is the runaway speed of a hydraulic turbine always kept twice its normal speed?
The runaway speed of a hydraulic turbine is the speed at which the turbine coupled to the generator runs at the maximum possible speed due to loss of load and this happens until the shut off valves completely closes the discharge from the penstock. the runaway speed of the turbine is determined by the turbine designer and is influenced by the maximum discharge of water from the penstock, the combined inertia of the turbine runner and the generator and the flywheel. this factor can vary from 1.5 up to 3 times the nominal speed of the turbine and is determined by the turbine designer considering all the load parameters.
