Explain the answers in full detail 

### Problem Statement

A two-dimensional square channel redirects a water flow from horizontal uniform to vertical nonuniform. The pipe width is \( h = 75.5 \, \text{mm} \). The pressure is \( 185 \, \text{kPa (abs)} \) at the inlet and at atmospheric pressure at the exit with \( v_{\text{max}} = 2v_{\text{min}} \). The mass of the pipe is \( M = 2.05 \, \text{kg} \). The internal volume of the pipe is \( V = 0.00355 \, \text{m}^3 \).

a. Find \( v_{\text{min}} \) if \( U = 7.5 \, \text{m/s} \).

b. Calculate the force exerted by the pipe assembly on the supply.

### Diagram Explanation

The diagram depicts a two-dimensional flow channel where water enters horizontally at velocity \( U \) and exits vertically. The flow transitions from a uniform horizontal flow to a nonuniform, vertical flow. The channel consists of:

- **Horizontal Section:** Water enters with a velocity \( U \) and width \( h \).
- **90-degree Bend:** Water is redirected upwards.
- **Vertical Section:** Water exits with velocities \( v_{\text{max}} \) and \( v_{\text{min}} \) at different points across the pipe.

### Calculations

1. **Find \( v_{\text{min}} \)**
    - Assume continuity and/or Bernoulli's principle may be used to solve this part.

2. **Calculate the Force**
    - Consider momentum conservation and force due to the pressure difference and weight of the pipe water system to determine the force exerted by the pipe assembly.

This context will enhance understanding for students on topics such as fluid dynamics, pressure-flow relationships, and forces in fluid systems.
