How do you make a catapult?
you make a catapult!
Is a mangonel a catapult or a bridge?
A mangonel is a catapult, not a bridge.
What is catapult ammo?
catapult ammo can be anything from cows, to boulders.
What are three different type of catapults?
There are more but these are just a few: Aircraft Catapult, Slingshot Catapult, and an Onager Catapult.
How does a catapult and ballista work?
Yes, it is a catapult. Just like a mangonel but not a trebuchet.
Who invented the steam catapult?
Commander Colin C. Mitchell of the Royal Naval Reserve. In 1954, he suggested taking steam from the ship's main boiler to power the aircraft catapult.
What is boiler combustion efficiency?
boiler efficiency is how much water is converting to steam.
A steam turbine has an efficiency of 40 percent A steam engine has an efficiency of 25.0 percent Suppose both devices are provided with 1000J of thermal energy How much more useful work will the ste?
The steam turbine will produce 400 J of output, and the steam engine 250 J. That's what the efficiency figure means.
What was discovered by James watt?
That the efficiency of a Steam Engine could be improved by condensing the exhaust steam.
How do you calculate the efficiency of vapour absorption machine?
how to calculate the vapour absorption mechine efficiency and per TR steam consumption
What improved the efficiency and design of newcomens steam engine?
James Watt
How does a catapult perform energy transformation?
Catapult can work in different ways. The most common catapult we think of to day is the steam catapult used on aircraft carriers. The steam isallowed to build up pressure and released when the pressure is high enough to move the weight of the plane. This pressure release pushes on a piston much like a cars. that piston is pushed down a shaft till the end of that shaft. the counter reaction is the plane moving in the other direction. Newtons law works once again. MKS
What is kenotometer?
A kenotometer is an instrument used in steam turbine condensers to measure the vacuum in the steam space of the condenser. The vacuum achieved by the condenser has significant influence on the efficiency of the steam turbine.
How is boiler efficiency calculated?
Boiler efficiency is calculated by determining the steam value per hour and dividing it by the amount of fuel which is consumed per hour. By doing this one can determine the efficiency of a boiler.
What is the efficiency of thermal power plant?
A modern combined cycle gas turbine/ steam turbine power plant can reach almost 60% efficiency.
Why is it advantageous to use steam as hot as possible in a steam driven turbine?
in practice;the steam MUST be in the superheated region before entering the turbine.superheated steam means there is not moister in the steam (dry steam)the reason is moister will damage the turbine blades.in theory;the hotter the temperature the better the efficiency (look up vapor power cycles)work done by the turbine = the enthalpy (at temp. of steam entering the turbine)- the enthalpy at the turbine exist.the efficiency = work done by the turbine / the heat input.
How do you calculate only turbine efficiency not turbine cycle efficiency?
by calculating the inlet steam enthalpy-outlet steam enthalpy we will know the total kcal consumed for output mw required kcal for 1 kwh=860 now campare this with your turbine kcal for 1kwh now you came to know how much is your turbine efficiency................................................................................
