Functions
FlowRateResult	pneumatic_valve::calculateFlowRate (const FlowRateInput &input)
	Calculates the air flow rate through a pneumatic valve with unit flow coefficient (Cv = 1).
CvResult	pneumatic_valve::calculateCv (const CvInput &input)
	Calculates the valve flow coefficient (Cv) for a pneumatic valve.

Variables
constexpr double	pneumatic_valve::kAirFlowFactor = 0.6875
	Empirical air flow constant for dry air at standard conditions (60°F, 14.696 psia).

Detailed Description

Provides two functions for pneumatic valve sizing in compressed air systems: one to calculate the theoretical air flow rate through a valve with a unit flow coefficient (Cv = 1), and one to calculate the valve flow coefficient (Cv) when the actual flow rate and operating pressures are known. All calculations use U.S. customary units.
