Answer:350.92 KJ/kg
Explanation:
Given the process is reversible adiabatic i.e it is isentropic
![P_1=5 MPa](https://tex.z-dn.net/?f=P_1%3D5%20MPa%20)
![T_1=4500 MPa](https://tex.z-dn.net/?f=T_1%3D4500%20MPa)
![P_2=1.4 MPa](https://tex.z-dn.net/?f=P_2%3D1.4%20MPa)
From steam table
![h_1=3317.03KJ/kg](https://tex.z-dn.net/?f=h_1%3D3317.03KJ%2Fkg)
For isentropic process ![s_1=s_2](https://tex.z-dn.net/?f=s_1%3Ds_2)
at ![P_2=1.4 MPa](https://tex.z-dn.net/?f=P_2%3D1.4%20MPa)
![s_2=6.82 KJ/kg-k](https://tex.z-dn.net/?f=s_2%3D6.82%20KJ%2Fkg-k)
![h_2=2966.11 KJ/kg](https://tex.z-dn.net/?f=h_2%3D2966.11%20KJ%2Fkg)
Therefore Work output of the turbine per unit mass of steam is =![h_1-h_2](https://tex.z-dn.net/?f=h_1-h_2)
=3317.03-2966.11
=350.92 KJ/kg
Answer:
Explanation:
There are two main ways to de-starch leaves of a plant - the 'Light Exclusion' Method and the 'Carbon Dioxide Deprivation' Method. The 'Light Exclusion' method is a simpler procedure and is used often. Leaves can be destarched by depriving them of light for an extended period of time, usually 24-48 hours.
Answer:
There are many examples of electrostatic phenomena, from those as simple as the attraction of the plastic wrap to one's hand after it is removed from a package to the apparently spontaneous explosion of grain silos, the damage of electronic components during manufacturing, and photocopier & laser printer operation
Wave speed = frequency * wavelength
Wave speed = 4 * 25
Wave speed = 100 m/s
A multi-cellular organism is not an exact copy of its parents because the offspring shares genes of both the parents.
<u>Explanation:</u>
- For a multi-cellular organism to reproduce, they require two parents.
- Characteristics are inherited from both the parents. So, an offspring can't b an exact copy of either of its parents.
- When a unicellular organism reproduce, they make an exact copy of its parent as they originate from only one parent.
- Punnett diagram is used to determine what all traits as organism is supposed to inherit from its parents.
- Chromosomes carry the blueprint of life from one generation to another.
- There are 46 chromosomes with 23 inherited from each parents through the process of mitosis. These chromosome makes up 23 pairs all together.
