Answer:
Explanation:
Given that the tank is insulated and rigid, heat transfer to the surrounding is zero and there is no change in volume of system(container).
p1=400kpa, T1= 40°c= 313k, p2=800kpa
volume of container = volume of cube= a³=1³=1m³
Air is acting as an ideal gas, hence, applying ideal gas equatin R= 287J/kg.k for air
a.) Process 1-2 constant volume process v1=v2
P∝T=
b.) According to first law of thermodynamics
δQ=0(insulated container)
where r= specific heat ratio; for air, r=1.4, R= 0.287KJ/kg.k
Then
The negative sign means work done of system is in reverse.
c.) Entropy generation = change in system + change in surrounding
change in surrounding is zero
change in system=
v1=v2; v2/v1=1; ln(1)=0
entropy gen= 4.453*0.7175*ln(626/313) + 0 =2.215KJ/k
Answer:
The area increase by 223.84m2 in the summer
Explanation:
There exist a linear or a direct relationship between the temperature and the area because as the temperature increases, the area increases and vice versa.
The detailed and step by step calculations is as shown in the attachment.
