Answer:
Exit velocity 
m/s.
Explanation:
Given:
At inlet:
Properties of steam at 100 bar and 600°C
At exit:Lets take exit velocity 
We know that if we know only one property inside the dome then we will find the other property by using steam property table.
Given that dryness or quality of steam at the exit of nozzle is 0.85 and pressure P=80 bar.So from steam table we can find the other properties.
Properties of saturated steam at 80 bar
So the enthalpy of steam at the exit of turbine
Now from first law for open system
In the case of adiabatic nozzle Q=0,W=0
m/s
So Exit velocity m/s.
Answer:
The answer is "Option B".
Explanation:
Given equation:
if
Calculating by the Routh's Hurwitz table:
Form the above table:
In the above, the value of k is greater than 1.
A material scientist investigates the characteristics of materials and their uses. Nature and human knowledge restrict the number of existing materials on Earth. This signifies that there is a limited amount of material available for use in the production of goods.
Given that they deal with the design and manufacturing of things, mechanical engineers sometimes lack the specialties seen in other branches of engineering. This necessitates a thorough understanding of all elements of engineering.
<h3>Why does Absolute Zero Exist?</h3>
Absolute zero, also known as zero kelvins, is equivalent to 273.15 degrees Celsius, or -459.67 degrees Fahrenheit, and represents the point on a thermometer where a system has the least amount of energy, or thermal motion. But there's a catch: absolute zero is unattainable, But exists as a measure of relativity.
Absolute zero is the temperature at which a thermodynamic system has the least amount of energy. It is equivalent to 273.15 degrees Celsius on the Celsius scale and 459.67 degrees Fahrenheit on the Fahrenheit scale.

Answer:
Explanation:
The functions of the following are as follows:
1). Oil Rings:
- Regulates oil within cylinder walls.
- Helps to keep cylinder walls lubricated
- Prevent Heat transfer
- Reduce friction between piston and cylinder
2). Fly Wheel:
- It is used to store rotational energy
- It resist any change in rotational speed due to its moment of inertia
- It helps to control the orientation of the mechanical system
3). Timing gears:
- It provides synchronization in the rotation of crankshaft and the camshaft so as to provide proper valve opening and closing time during each cylinder's stroke(intake and exhaust).
