pnge-engineering-science

Tutoring agent for WVU PNGE undergraduate courses in petroleum engineering, chemical engineering minor, and engineering foundations. Helps students solve homework problems, understand course concepts, work through derivations, and apply engineering skills to real petroleum systems. Orchestrates computational skills (pnge-mechanics, frac-design, wellbore-stability, mass-energy-balance, tnav) and data skills to ground course material in real data. Use when a student asks for help with a PNGE homework problem, needs a concept explained for a course, wants to check their work on a calculation, needs help with units or equation setup, or wants to see a worked example from Marcellus or Appalachian context. Trigger for phrases like "help me solve this PNGE problem", "explain reservoir pressure decline", "how do I calculate fracture width", "work through this mass balance", "check my answer for casing stress", or any request for coursework assistance in petroleum or chemical engineering.

Solve aqueous chemistry and electrochemistry problems relevant to chemical, petroleum, and environmental engineering including pH and pOH, buffers, alkalinity and hardness conversions, ionic strength, solubility and precipitation screening, Nernst equation, electrochemical cell potentials, Faraday law, and corrosion-cell fundamentals. Use when the user asks about pH, buffering, acid-base speciation, alkalinity as CaCO3, hardness, precipitation risk, redox potential, electrolysis, galvanic cells, or electrochemical corrosion. Trigger phrases include aqueous chemistry, electrochemistry, pH, alkalinity, hardness, Nernst, Faraday, buffer, precipitation, ionic strength, or corrosion cell.

Fluid mechanics for chemical and petroleum engineers covering pipe flow, Bernoulli equation, Reynolds number, friction factors, and pump sizing. Implements Darcy-Weisbach pressure drop, Colebrook-White friction factor iterative solution, Blasius smooth-pipe correlation, mechanical energy balance with pump work and friction losses, pump power, venturi and orifice flow measurement, and hydrostatic pressure calculations. Use when the user asks about Reynolds number, laminar or turbulent flow, friction factor, Darcy-Weisbach equation, Moody diagram, pipe pressure drop, Bernoulli equation, pump head or power, NPSH, flow measurement, continuity equation, minor losses, fitting loss coefficients, or any pipe flow calculation.
