Explanation:
Answer:
(a) Work out put=692.83
(b) Change in specific entropy=0.0044
Explanation:
Properties of steam at 1 MPa and 200°C
We know that if we know only one property in side 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 turbine is 0.83 and temperature T=40°C.So from steam table we can find pressure corresponding to saturation temperature 40°C.
Properties of saturated steam at 40°C
So the enthalpy of steam at the exit of turbine
(a)
Work out put =
=2827.4-2134.57
Work out put =692.83
(b) Change in specific entropy
Change in specific entropy =0.0044
Answer:
Ψ = 10(y^2) + c
<em><u>y = 1.067m</u></em>
Explanation:
since the flow is one dimensional in positive X direction, the only velocity component is in X, which is denoted by u
while u is a function of y
we find the u in terms of y; u varies linearly wih y
we use similiraty to find the relation
32/1.6 =<em>u/y</em>
<em><u>u = 20y</u></em>
<em><u>Ψ = ∫20ydy</u></em>
<em><u>Ψ = 10(y^2) + c</u></em>
<em><u>(b)</u></em>
<em><u>the flow is half below y = 1.6*(2/3)=1.067 m</u></em>
<em><u>this is because at two third of the height of a triangle lies the centroid of triangle. since the velocity profile forms a right angled triangle , its height is 1.6 m . the flow is halved at y = 1.067m</u></em>
