If we have an air flow in a tube that had d=0.5m however the diameter of the air flow on the inlet side is only 0.2m with a velocity of 0.13m/s. By simulating it through fluent we observe the occurrence of two regions one laminaire and the other is turbulent. The problem is that this observation is against what Reynolds states since for such a velocity and diameter we tend to have Re=1800 witch means just laminar region can u explain why did the turbulence occurred?

find the surface area of the sphere to the nearest square unit. use a calculator.

a. 254 in.2

b. 64 in.2

c. 127 in.2

d. 1,018 in.2

can u provide the graph and if its not possible

then i can tell u the segment where the

average time interval starts degrading is the segment where the car is slowing down

the speed of the cart after 3 seconds of low fan speed is ⇒ 54.0 cm/s.

the speed of the cart after 5 seconds of medium fan speed is ⇒ 120.0 cm/s.

the speed of the cart after 2 seconds of high fan speed is ⇒ 64.0 cm/s. 

just did the lab.
