**Design Task**
Create a radially‑symmetrical inlet nozzle for a sub‑mersible vacuum that must pick up sand, silt, leaves, nuts, and rocks from a pool.

**Operating Conditions**
- Depth: ___ m (hydrostatic pressure ___ bar)
- Vacuum pump: ___ kPa pressure drop, ___ L min⁻¹ flow rate
- Particle size range: ___ mm – ___ mm

**Design Question**
Let *h* be the height of the leading edge of the inlet lip. How should the nozzle’s cross‑sectional area A(h) vary from the tip to the entrance of the debris chamber? Does A(h) **increase, decrease, stay constant, or oscillate**? Explain with fluid‑dynamic reasoning.

**Required Output**
1. Parametric profile r = f(h) (or CAD sketch).
2. Physical justification (Bernoulli, continuity, drag, etc.).
3. Preliminary CFD/analytical results (pressure/velocity fields).
4. Prototype‑test plan.
5. Identified failure modes and mitigation ideas.

Prompt (Manufacturing Realistic, Engineering Validated, Battery Powered, Shark Inspired)

A photorealistic underwater scene of a battery powered, manually guided submersible pool vacuum designed in the form of a hammerhead shark, engineered for reliable residential pool cleaning. The hammer shaped head functions as a wide suction nozzle, resting against the pool floor with a controlled standoff gap that prevents suction lock. The nozzle perimeter incorporates a segmented compliant rubber skirt with relief channels and a short, low drag brush edge, allowing conformity to uneven plaster or aggregate while maintaining consistent debris pickup without full surface sealing. The intake opening is wide, functional, and evenly distributed across the hammerhead width, with internal geometry implied to promote uniform suction and reduce debris bridging. No decorative elements are present at the intake. The shark inspired body is compact, structurally stiff, and mechanically plausible, housing a sealed internal battery, electric pump, and debris canister. The overall form reads clearly as a hammerhead shark silhouette in plan view, but uses simplified, utilitarian geometry optimized for injection molding, including broad radii, uniform wall thickness, visible draft, and minimal, logical part seams. A single, modestly sized clear inspection window with generous radii reveals collected debris inside the canister, integrated as a structurally supported feature rather than a dominant cosmetic element. Filtered water exits through two wide, diffused, symmetrical outlet ports near the rear, angled slightly downward and rearward to minimize jet velocity, eliminate lateral thrust, and avoid lift or self propulsion. Outlet flow appears calm and balanced. A subtle shark tail form extends rearward into a reinforced, standard pool pole interface, positioned close to the nozzle plane and near the center of resistance to reduce pitch, improve stability, and minimize user fatigue. The pole connection is realistic, robust, anti rotation, and compatible with common residential pool poles. The vacuum rests stably on the pool floor, slightly negatively buoyant, with no visible lift, hovering, or rocking. The stance appears planted and predictable. Materials appear chemically durable and pool safe: matte gunmetal gray structural housing, deep aqua teal functional accents, black elastomer skirt and seals, and thick transparent acrylic or polycarbonate for the inspection window. Finishes are lightly textured, non glossy, and practical, with no showroom polish. No exposed electronics, charging ports, cords, or hoses are visible underwater. The design communicates sealed, pressure tolerant construction suitable for repeated submersion. Environment: crystal clear residential pool water with light plaster or aggregate floor, scattered leaves and sand actively being pulled into the nozzle. Gentle natural daylight with subtle underwater caustics. Camera: low angle view aligned with the pool floor, looking along the length of the vacuum. Entire vacuum head in focus, background softly blurred. Style: photorealistic, ultra detailed, physically accurate materials, correct scale and proportions, engineering realistic, clean minimal background, no text, no logos.
