Answer: 
, 
Explanation:
Since there is no information related to volume flow to and from turbine, let is assume that volume flow at inlet equals to 
. Turbine is a steady-flow system modelled by using Principle of Mass Conservation and First Law of Thermodynamics:
Principle of Mass Conservation
First Law of Thermodynamics
This 2 x 2 System can be reduced into one equation as follows:
The water goes to the turbine as Superheated steam and goes out as saturated vapor or a liquid-vapor mix. Specific volume and specific enthalpy at inflow are required to determine specific enthalpy at outflow and mass flow rate, respectively. Property tables are a practical form to get information:
Inflow (Superheated Steam)
The mass flow rate can be calculated by using this expression:
Afterwards, the specific enthalpy at outflow is determined by isolating it from energy balance:
The enthalpy rate at outflow is:
Answer:Non-uniform motion
Explanation:
This is an example of Non-uniform motion because unequal distance traveled by an object in equal interval of time is termed as Non-Uniform motion and here also the distance traveled by object is 1 ft ,4 ft and 8 ft which is different from each other.
In Uniform motion distance traveled is equal in equal interval of time .
True I think I’m not sure?
Explanation:
Strengthening is the method to improve the strength of material because different type of material property requires for different requirement .Some times requires more ductility,some time requires more strength.
When impurities are mixed with the pure metal then the strength of metal will increases and this is called the strengthening of metal.
The methods of strengthening are as follows
1.Solid solution strengthening and alloying
2.Work hardening
3.Transformation hardening
4.Grain boundary strengthening
5.Precipitation hardening
