Answer:
R= 1.25
Explanation:
As given the local heat transfer,
But we know as well that,
Replacing the values
Reynolds number is define as,
Where V is the velocity of the fluid and \upsilon is the Kinematic viscosity
Then replacing we have
<em>*Note that A is just a 'summary' of all of that constat there.</em>
<em>That is 
</em>
Therefore at x=L the local convection heat transfer coefficient is
Definen that we need to find the average convection heat transfer coefficient in the entire plate lenght, so
The ratio of the average heat transfer coefficient over the entire plate to the local convection heat transfer coefficient is
Answer:
In ferrous metal iron present but on the other hand in the non ferrous material iron does not present.That is why there is a different heat treatment process for ferrous and nonferrous materials.
Ferrous materials contains iron is the main constitute.Like steel ,cast iron ,wrought iron .Steel and cast iron are the alloy element of iron ans carbon.Wrought iron is the purest from of iron.
Heat treatment process for ferrous materials :
1.Normalizing
2.Annealing
3.Quenching
4.Surface hardening
Heat treatment process for non ferrous materials :
Mostly annealing process is used for non ferrous materials.After annealing non ferrous will become soft.
When two metal plates are joined then they form a bimetallic structure.The bimetallic structure is used to find the relationship of thermal temperature and the mechanical displacement.
The use of bimetallic structure -In clock ,thermometers ,engines.
They are health care professionals that focus on the safe and effective use of medications
Answer:
Heat transfer = 2.617 Kw
Explanation:
Given:
T1 = 300 k
T2 = 440 k
h1 = 300.19 KJ/kg
h2 = 441.61 KJ/kg
Density = 1.225 kg/m²
Find:
Mass flow rate = 1.225 x [1.3/60]
Mass flow rate = 0.02654 kg/s
mh1 + mw = mh2 + Q
0.02654(300.19 + 240) = 0.02654(441.61) + Q
Q = 2.617 Kw
Heat transfer = 2.617 Kw
