Explanation:
In the given excerpt, there was a national depth expansion that was as a result of the war that occurred between 1939 and 1945. The war led to the destruction of basic amenities and infrastructures as well as buildings. This ultimately created national depth. It also cost a significant amount to rebuild from scratch.
Answer:
Honestly overall i think it looks fantastic
Explanation:
It looks like some really nice clean craftsmanship and i love the use of some different colors for some drawers to make it pop. the only con that i can possibly think of is that with it being wood and you moving it from place to place, some rubber feet or something that would prevent it from scratching/damaging anything else if it doesn't already (cant really see under it). other then that one thing i think it looks really good. well done.
Answer:
0.163 MW
Explanation:
To get the minimum rate of energy rehection by heat transfer to cold reservoir, it implies that the power cycle operates in reversible cycle. The efficiency of reversible cycle whose value will be same as efficiency of power cycle will be given by
Efficiency of reversible cycle
n= (Th-Tc)/Th where T represent temperature, n efficiency, subscripts h and c hot and cold respectively
Substituting 500 and 310 for hot and cold temperatures respectively then efficiency
n=(500-310)/500=0.38
Efficiency of power cycle, n= Power output/Qh
Qh= 0.1/0.38= 0.263
Net power output, W= Qh- Qc
Qc=Qh-W= 0.263-0.1=0.163 MW
Answer:
a) The flow capacity of the fan is 3150 L/min
d) the minimum diameter is 0.11 m
Explanation:
given data:
A = area of residence = 200 m²
h = height of building = 2.7 m
Percentage of air that must be replaced by fresh air is 35%
v = velocity of air in the duct = 5.5 m/s
a) The volume of the entire building is:
The flow capacity of the fan is equal to:
b) The volume flow rate of fresh air is equal to:
