Answer:
BMEP = 8.904 bar
IMEP = 11.13 bar
Explanation:
given data
area A = 3250 mm²
length L = 73 mm
calibration factor = 0.2 bar/mm
mechanical efficiency = 80 %
to find out
IMEP and the BMEP
solution
first we calculate the BMEP break mean efficiency pressure tat is express as
BMEP = 
here A is area and L is length
so BMEP is
BMEP = 
= 44.52 mm
BMEP = 44.52 × 0.2 bar = 8.904 bar
and
we know mechanical efficiency is
mechanical efficiency = 
so put here value we get IMEP
IMEP = 
IMEP = 11.13 bar
Answer:
he didn't use the proper material
Answer:
a)True
Explanation:
Rolling:
Rolling is a metal forming in which a material passes through two or more than two depends on conditions,rolls to produce the desired product.
Ring rolling:
In ring rolling a thick ring compresses by rolls to produce the large diameter ring.Actually volume of material is constant so when diameter of ring increases then to compensate it, the thickness of ring reduces .In simple words we can say that in ring rolling a thick ring of smaller is rolled into a thin ring of larger diameter.
Answer:Even though EPA regulates and sets standards for public drinking water, many Americans use a home water treatment unit to: Remove specific contaminants. Take extra precautions because a household member has a compromised immune system. Improve the taste of drinking water.
