Q2) Water flows through a pipe as shown in Figure Q2. The diameter at point 2 is half of the diameter at point 1. Assume there is no change in density and viscosity of water between points 1 and 2. Figure Q2 a) Derive a formula that shows the relationship between velocity at point 1 (v1) and velocity at point 2 (v2) b) Derive a formula that shows the relationship between the Reynolds Number at point 1 (Rel ) and the Reynolds Number at point 2 (Re2). (Hint : Use the formula of the relationship between vl and v2 derived from above question)

Question
Q2) Water flows through a pipe as shown in Figure Q2. The diameter at point 2 is half of the diameter
at point 1. Assume there is no change in density and viscosity of water between points 1 and 2.
Figure Q2
a) Derive a formula that shows the relationship between velocity at point 1 (v1) and velocity at
point 2 (v2)
b) Derive a formula that shows the relationship between the Reynolds Number at point 1 (Rel
) and the Reynolds Number at point 2 (Re2). (Hint : Use the formula of the relationship between
vl and v2 derived from above question)
