Calculates the partial pressure of a gas at sea-level or a specified depth.

Example

let diveKit = DiveKit.default
let gasCalculator = DKGasCalculator(with: diveKit)

do {
    // Calculate partial pressure of component gases in EANx32 at 99 feet.
    let gas = try Gas.enrichedAir(32)
    let partialPressure = try gasCalculator.partialPressure(of: gas, at: 99)
    print(partialPressure) // PartialPressure(oxygen: 1.28, nitrogen: 2.72, trace: 0.0)
} catch {
    // Handle Error
    print(error.localizedDescription)
}

Calculates surface air consumption of a diver

Example

let gasCalculator = DKGasCalculator.init()

do {
    // Calculate SAC rate
    let surfaceAirConsumption = try gasCalculator.surfaceAirConsumption(at: 33, for: 10, consuming: 200)
    print(surfaceAirConsumption.value) // 10.0
} catch {
    // Handle Error
    print(error.localizedDescription)
}

Calculates surface air consumption of a diver

Example

let gasCalculator = DKGasCalculator.init()

do {
    // Calculate SAC rate
    let surfaceAirConsumption = try gasCalculator.surfaceAirConsumption(at: 33, for: 10, startGas: 2400, endGas: 2200)
    print(surfaceAirConsumption.value) // 10.0
} catch {
    // Handle Error
    print(error.localizedDescription)
}

Calculates the respiratory minute volume of a diver.

Example

let gasCalculator = DKGasCalculator.init()

do {
    // Calculate RMV Rate
    let tank = DKTank(ratedPressure: 3000, volume: 80, type: .aluminumStandard)
    let respiratoryMinuteVolume = try gasCalculator.respiratoryMinuteVolume(at: 33, for: 10, with: tank, consuming: 200)
    print(respiratoryMinuteVolume.round(to: 2)) // 0.27 (ft3/min)
} catch {
    // Handle Error
    print(error.localizedDescription)
}

Calculates the respiratory minute volume of a diver.

Example

let gasCalculator = DKGasCalculator.init()
do {
    let tank = DKTank(ratedPressure: 3000, volume: 80, type: .aluminumStandard)
    let surfaceAirConsumption = try gasCalculator.surfaceAirConsumption(at: 33, for: 10, startGas: 1700, endGas: 1500)
    let respiratoryMinuteVolume = try gasCalculator.respiratoryMinuteVolume(for: surfaceAirConsumption, with: tank)
    print(respiratoryMinuteVolume.round(to: 2)) // 0.27 (ft3/min)
} catch {
    // Handle Error
    print(error.localizedDescription)
}

Calculates air consumption of a diver at depth

Example

let gasCalculator = DKGasCalculator.init()
do {
    // Calculate DAC rate
    let depthAirConsumption = try gasCalculator.depthAirConsumption(for: 10, consuming: 200)
    print(depthAirConsumption) // 20.0
} catch {
    // Handle Error
    print(error.localizedDescription)
}

Calculates the respiratory minute volume of a diver.

Example

let gasCalculator = DKGasCalculator.init()
do {
    // Calculate RMV Rate
    let tank = DKTank(ratedPressure: 3000, volume: 80, type: .aluminumStandard)
    let respiratoryMinuteVolume = try gasCalculator.respiratoryMinuteVolume(
        gasConsumed: 200,
        tank: tank,
        depth: 33,
        time: 10)
    print(respiratoryMinuteVolume) // 0.27 (ft3/min)
} catch {
    // Handle Error
