As speed increases in an engine with throttle body fuel
injection, does the temperature of the air-fuel mixture at the
intake manifold exit increase or decrease? Explain what parameters
affect your answer.
1. Which response serves to decrease body temperature if body
temperature increases above its normal range?
Question 2 options:
constriction of blood vessels in the dermis
increased contraction of skeletal muscles
increased secretion of sweat from sweat glands
2.Where in the epidermis is new cell division most likely to
occur?
stratum basale
stratum corneum
stratum granulosum
stratum lucidum
3. How long is a keratinocyte typically part of the epidermis
before it is sloughed off of the apical surface?
Question 8...
At what temperature does the rms speed of
a.) A nitrogen molecule equal the escape speed from the Earth’s
surface and
b.) A hydrogen molecule equal the escape speed from the Earth’s
surface?
c.) You will find that these temperatures are very high, so you
might think that the earth’s gravity could easily contain both
gases. But not all molecules move with vrms. There is a
distribution of speeds, and a small percentage of molecules have
speeds several times vrms....
An in-line, six-cylinder, 6.6-liter, four-stroke cycle
SI engine with multipoint port fuel injection operates át 3000 RPM,
with a volumetric efficiency of 89% and AF of
15:1. The engine has bore and stroke'related by S = 0.90 B. The
engine has an exhaust pipe between engine and catalytic converter
that can be approximated as a round pipe, 1.5 m long and 6.5 cm
inside diameter. Exhaust temperature leaving the engine is 477°C,
and the average wall temperature of the exhaust...
