	Calculates heat loss for a tank wrapped in insulation.
InsulatedTankOutput	bareTankHeatLoss (const InsulatedTankInput &input)
	Calculates heat loss for an uninsulated (bare) tank.
double	rayleighNumber (double thermal_expansion, double surface_temperature, double ambient_temperature, double diameter, double kin_viscosity, double thermal_diffusivity)
	Computes the Rayleigh number for natural convection along a vertical cylinder in U.S. customary units.
double	naturalConvectionCoefficient (double rayleigh, double conductivity, double diameter)
	Computes the natural convection heat transfer coefficient for a vertical cylinder using the Ra^(1/3) empirical correlation.

Detailed Description

Provides a function-based API for estimating heat loss and annual energy cost for a hot vertical cylindrical tank, with or without thermal insulation. Air properties are evaluated at the ambient temperature using fourth-order polynomial fits to tabulated U.S. customary air data. The calculation uses gravitational acceleration g = 32.174 ft/s² and the Stefan–Boltzmann constant in BTU/(hr·ft²·°R⁴).
