Explanation:
Solution
The first step is to find the pipe cross section at the inlet section
Now,
A₁ = π /4 D₁²
D₁ = diameter of the pipe at the inlet section
Now we insert 8 cm for D₁ which gives us A₁ = π /4 D (8)²
=50.265 cm² * ( 1 m²/100² cm²)
= 5.0265 * 10^⁻³ m²
Secondly, we find cross section area of the pipe at the inlet section
A₂ = π /4 D₂²
D₂ = diameter of the pipe at the inlet section
Now we insert 5 cm for D₁ which gives us A₁ = π /4 D (5)²
= 19.63 cm² * ( 1 m²/100² cm²)
= 1.963 * 10^⁻³ m²
Now,
we write down the conversation mass relation which is stated as follows:
Q₁ = Q₂
Where Q₁ and Q₂ are both the flow rate at the exist and inlet.
We now insert A₁V₁ for Q₁ and A₂V₂ for Q₂
So,
V₁ and V₂ are defined as the velocities at the inlet and exit
We now insert 5.0265 * 10^⁻³ m² for A₁ 5 m/s for V₁ and 1.963 * 10^⁻³ m² for A₂
= 5.0265 * 5 = 1.963 * V₂
V₂ = 12.8 m/s

Answer:
See attachment for complete answer step by step solving
Explanation:
Given that:
The anchor shown is used to tie tower guy cables to the ground and is supported by a distributed force from the soil, which can be approximated as shown. The anchor also is subjected to the loads shown, where P1 = 5 kNand P2 = 3 kN . The anchor is made from aluminum with E = 69 GPa . It is a cylindrical rod with diameter d1 = 4 cm with three segments of length L = 2 m . One end of the rod is linearly tapered to a diameter of d2 = 2 cm.
a. Calculate the intensity of the reaction load, Po
b. Use the reaction found in Part A, po = 13 kN/m , and calculate the total change in length for the anchor.
