3. Determine the bulk temperature, center line temperature, and surface temperature for a laminar flow in a 2 cm inner diameter
tube with defined velocity and temperature profiles: a. u=0.1[1-(r/0.01)^2] m/s b. T=400-3x10^6(1.875x10^-5-0.25r^2+624r^4) K c. Calculate the heat flux at the wall and the Nusselt number if the fluid is water (look up the property of water) d. Calculate the pressure drop in the tube over 10 cm.

Answer: A (-2, 3)
Step-by-step explanation:
1. To know which oredered pairs does not lie on the graph, you must substitute the x-coordinate of each one of thm into the function and if you obtain the y-coordinate shown in that ordered pair, then that point lies on the graph.
2. Therefore, you have:
A. x=-2
(It does not lie on the graph).
B. x=--1
(It lies on the graph).
C. x=3
(It lies on the graph).
D. x=4
(It lies on the graph).
Therefore, the answer is the option A.
