Answer:
specific volume = 1.025 m³/kg
Explanation:
given data
total mass m1 +m2 = 80 kg
specific volume = 0.8 m³/kg
occupies volume v1 = 40 m³
other gas specific volume = 1.4 m³
to find out
How much volume is occupied by the second gas and what is the specific volume of the mixture
solution
we know that density is reciprocal of specific volume and here gas is not interacting
so total specific volume is assume so ratio is total volume to total mass
and
specific volume = 
here ρ is density
so ρ1 = 
= 1.25 kg/m³
and ρ2 = 
= 0.714 kg/m³
and
so m1 = ρ1v1 = 1.25 × 40 = 50 kg
and m2 = 80 - 50 = 30 kg
so
v2 = 
v2 = 
= 42 m³
so volume occupied by second das = 42 m³
and
specific volume of mixture will be
specific volume of mixture = 
specific volume = 
specific volume = 1.025 m³/kg
Answer: CARDINALITY RATIO AND PARTICIPATION
ADVANTAGE
CARDINALITY RATIO
(THEY ARE USED TO SIMPLIFY DESIGNS)
DISADVANTAGE OF CARDINALITY RATIO IS THAT
(YOU CAN NOT SPECIFY A GIVEN NUMBER TO BE MAXIMUM)
ADVANTAGE OF PARTICIPATION CONSTRAINT IS THAT
(IT SHOWS WETHER THE EXISTENCE OF AN ENTITY IS DEPENDENT ON ITS RELATIONSHIPS WITH ANOTHER ENTITY)
DISADVANTAGE OF PARTICIPATION CONSTRAINT
(IT IS A COSTLY AFFAIR USING BOTH MODELS TO EXPRESEE RELATIONSHIPS).
Explanation:CARDINALITY RATIO specifies that maximum number of relationships an entity can engage itself in.
Participation constraint is a constraint that
Specifies whether the existence of an entity depends on its Relationships to another entity, it specifies the the minimum number of relationship instances that an entity can participate in
It is also minimum cardinality constraint,it has two types named as Total participation and partial participation.
