Answer:
A good one
Explanation:
Rotatianal degrees and stuf for different types of movement would take some proccesing power and if it were linked to brain neurons you would need one not prone to frying
Answer:429.8 KW
Explanation:
carbon dioxide Inlet temperature and pressure 100 KPa
At given Temperature and presssure
Flow rate
Steam Outlet temperature and Pressure is and pressure is 600 KPa
Heat loss 50 KW
Applying Steady Flow Energy Equation
Neglecting Kinetic and Potential Energy changes
Negative sign indicates work is being done on the system.
Maximum shear stress in the pole is 0.
<u>Explanation:</u>
Given-
Outer diameter = 127 mm
Outer radius, = 127/2 = 63.5 mm
Inner diameter = 115 mm
Inner radius, = 115/2 = 57.5 mm
Force, q = 0
Maximum shear stress, τmax = ?
τmax
If force, q is 0 then τmax is also equal to 0.
Therefore, maximum shear stress in the pole is 0.
Answer:
0.45516
Explanation:
ENTROPY : Entropy is a measure of molecular disorder it is denoted by S. Entropy is also measured in terms of thermal energy and temperature it is equal to thermal energy per unit temperature.
from the table S₁=1.99194 KJ/kg.k (at 400k)
from the table S₂=2.21952 KJ/kg.k (at 500k)
so total entropy change is given by =m (S₂-S₁)
=2(2.21952-1.99194)
=0.45516
The temperature at stagnation point is 78246K. The answer is an overestimate of the actual value.
<u>Explanation:</u>
Given:
Mach number, M = 38
Atmospheric temperature, Tₐ = 270K
γ = 1.4
Temperature at the station point, Tₓ = ?
We know,
Tₓ = 270 X [ 1 + (38*38) X (1.4-1) /2]
Tₓ = 270 X [ 1 + 577.6/2]
Tₓ = 270 X [1 + 288.8]
Tₓ = 270 X 289.8
Tₓ = 78246K
Therefore, the temperature at stagnation point is 78246K which seems to be inaccurate because the assumption of a calorically perfect gas holds good up to M = 5.
The answer is an overestimate of the actual value.
