Answer:
The mass flow rate of cooling water required to cool the refrigerant is .
Explanation:
A condenser is a heat exchanger used to cool working fluid (Refrigerant 134a) at the expense of cooling fluid (water), which works usually at steady state. Let suppose that there is no heat interactions between condenser and surroundings.The condenser is modelled after the First Law of Thermodynamics, which states:
The mass flow rate of the cooling water is now cleared:
Given that ,
,
and
, the mass flow of the cooling water is:
The mass flow rate of cooling water required to cool the refrigerant is .
Answer:
The duration of the consolidation process for the same clay is 32 min
Explanation:
for clay 1:
t1=0
H1=thickness=2 cm
for the clay 2:
t2=?
H2=2 cm
The time factor is equal to:
where Cv is the coefficient of consolidation
if Cv is constant, we have:
Clearing t2:
t2=32 min
