Aflat plate of width 1 m and length 0.2 m is maintained at a temperature of 32°c. ambient fluid at 22°c flows across the top of the plate in parallel flow. determine the average heat transfer coefficient, the convection heat transfer rate from the top of the plate, and the drag force on the plate for the following:

(a) the fluid is water flowing at a velocity of 0.5 m/s.
(b) the nanofluid of example 2.2 is flowing at a velocity of 0.5 m/s.
(c) water is flowing at a velocity of 2.5 m/s.
(d) the nanofluid of example 2.2 is flowing at a velocity of 2.5 m/s.

as we know our atmosphere or air have different levels. every level has other gasses, and every gas has another permeability. when the light comes from lower permeability to higher permeability, it changes its direction. so that means that when the light comes from the moon to the earth, it changes it's direction many more times. it basically means that the shape of the light part of the moon is changed on the earth.

the components of a vector are the parts of the vectors that are to each other.

b perpendicular

the answer is the first electromagnet (a). this is because it has more coils around the ferromagnetic material. increasing the number of coils increases the surface area in which the metal interacts with the current in the coil. this enables more atoms in the metal to become aligned hence becoming more magnetized.

just took the test its not "d"
