Answer:
50%
Explanation:
<u>Given information</u>
Cooling load=50 kW
COP=2
Consumption=50 kW
<u>Calculations</u>
Revised input is given by cooling load/COP=50/2=25 kW
Efficiency= Work output/ Revised input=25/50=0.5
Efficiency=0.5*100=50%
Answer:
f = 0.04042
Explanation:
temperature = 0°C = 273k
p = 600 Kpa
d = 40 millemeter
e = 10 m
change in P = 235 N/m²
μ = 2m/s
R = 188.9 Nm/kgk
we solve this using this formula;
P = ρcos*R*T
we put in the values into this equation
600x10³ = ρcos * 188.9 * 273
600000 = ρcos51569.7
ρcos = 600000/51569.7
=11.63
from here we find the head loss due to friction
Δp/pg = feμ²/2D
235/11.63 = f*10*4/2*40x10⁻³
20.21 = 40f/0.08
20.21*0.08 = 40f
1.6168 = 40f
divide through by 40
f = 0.04042
Answer:
birds-eye view perspective
Explanation:
If someone asked me to design an office building, I would draw it from a birds-eye view perspective. I would draw it this way so I could map out where everything in the office would go and make sure I have enough space for everything. I would also draw it this way in order to clearly see where everything would go in the office. For instance, cubicles/desks could go in the bottom left corner, while the boss's office could go in the top right. It would be easier to organize and it would be easier for me to look back on when I need to actually design the office later.
(i'm not sure if this is what your question is asking for so i just made my best guess)
Answer:
i hope this helps.
Explanation:
they are used for breaking concrete, can be positioned to break vertical and overhead surfaces, allows precisely chip away only specific areas.
