Answer: Temperature T = 218.399K.
Explanation:
Q= 129W/m2
σ = 5.67 EXP -8W/m2K4
Q= σ x t^4
t = (Q/σ)^0.25
t= 218.399k
We have that the relationships between users and per missions defined is given as
a) The relationship may <u>want </u>to be described as o(n p u x).(5)
b) he <em>relationship </em>ought to be described as o(n*s*u*x).
<h3>DAC scheme & RBAC scheme</h3>
a)
Generally, The relationship may <u>want </u>to be described as o(n*p*u*x)
X is a random cost, structured greater on organizational shape and culture.
b)
Finally, the relationship ought to be described as o(n*s*u*x).
X here is some possibly random fee, established greater on organizational shape and culture
is the wide variety of structures that manipulate their personal roles

Answer: New wheels should be re-torqued after the first 50 to 100 driving miles. This should be done in case the clamping loads have changed following the initial installation due to the metal compression/elongation or thermal stresses affecting the wheels as they are breaking in, as well as to verify the accuracy of the original installation.
Answer:
the work required by a reversible pump operating with the same conditions, in kW is 16.39 kW
the isentropic pump efficiency is 78%
Explanation:
Given that;
m = 1.2 kg/sec
T = 50 degree Celsius { Vf = 0.001012 m^3/kg}
P1 = 1.5 Mpa
P2 = 15 Mpa
W-actual = 21 kw
W reversible = m*Vf (p2 - p1)
= 1.2 * 0.001012 * ( 15*10^3 - 1.5*10^3)
= 1.2 * 0.001012 * 13500
= 16.39 kW
the work required by a reversible pump operating with the same conditions, in kW is 16.39 kW
Isentropic Pump efficiency = W-reversible / W-actual
= 16.39 / 21 = 0.78
= 78%
the isentropic pump efficiency is 78%
