The answer is "0.0728"
Explanation:
Given value:


if
flow is chocked
if
flow is not chocked
When P= 10 psia <
not chocked

Answer:
Density of oil will be 897.292 kg
And specific gravity of oil will be 0.897
Explanation:
We have given density of oil is 1.74 slugs/
We have to convert this slugs/
into kg/
We know that 1 slugs = 14.5939 kg
So 1.74 slug = 1.74×14.5939 = 25.3933 kg
And 1 cubic feet = 0.0283 cubic meter
So 
Now we have to calculate specific gravity it is the ratio of density of oil and density of water
We know that density of water = 1000 kg/
So specific gravity of water
