Dvelop a sequential flow diagram and a sequential vi in

Question

Develop a sequential flow diagram (or pseudocode) and a sequential VI in LabVIEW that illustrates how to solve the following problem, and provides a correct solution.

The construction of a pier on the LA coast has brought concern to local environmentalists who are looking at several issues that may affect wildlife in close proximity to the construction. Acoustics engineers are focusing on one particular aspect of the problem which involves the pressure waves (sound) generated from the operating construction equipment. Sound pressure level (SPL) is measured by the following equation:

SPL = 20log10(P/P_ref)

Where:

- SPL is the sound pressure level measured in decibels (dBs),
- P is the sound pressure measured in Pascal (Pa) and
- ref P is the reference pressure (Pa).

The reference pressure of ocean water is typically 1X10^-11 bars. Scientific studies have found that fish exposed to SPLs exceeding 190 dBs have experienced internal hemorrhaging. It is your job to estimate the maximum sound intensity (in W/m²) that can be experienced in the water without harming any of the aquatic wildlife in the immediate area.

Assume a particle in the traveling sound wave is moving at a velocity of 278 ft/s. Sound pressure is related to sound intensity by the following equation:

Where:

- P is the sound pressure in Pa,
- l is the sound intensity in W/m² and
- v is the particle velocity in m/s.

Part A:

Create a detailed sequential flow diagram of a model that solves the above question. Make sure your algorithm is flexible so that "particle velocity" and "reference pressure" and "SPL" can be modified (i.e. these should be variables, not constants). In your flow diagram, be sure to include output messages that display the units of all the inputs and outputs. Create your flow diagram on paper and insert the images in a PowerPoint or use PowerPoint directly.

Save your flow diagram in a PowerPoint named PA_4_2_NetID_sec.pdf

Note: Remember that you can create your flow diagram in another program such as VUE as introduced in class, or you can also do it in word, however, you need to paste the image into your PowerPoint slide.

Hint 1: Convert your units as you go as part of the flow of the problem.

Hint 2: 1 bar = 10⁵ Pa, 1 in = 2.54 cm

Part B:

Translate the graphical flow diagram developed in PART A into a LabVIEW VI to solve the problems being asked in the problem statement. (In your VI, you should include a break point in the formula block.)
