Humidity rate . High humidity in the oven, represented by an elevated wet-bulb temperature, increases the thermal conductivity of the air around the baked item, leading to a quicker baking process or even burning. Conversely, low humidity slows the baking process down. Humidity Humidity is the amount of water vapour present in air. Water vapour, the gaseous state of water, is generally invisible to the human eye. Humidity indicates the likelihood for precipitation, dew, or fog to be present. The amount of water vapour needed to achieve saturation increases as the temperature increases. As the temperature of a parcel of air
Crankcase ventilation system breather. To achieve this, the crankcase air inlet is usually ducted to the engine's air cleaner. The breather is usually provided with baffles and filters to prevent oil mist and vapour from fouling the air filter. Intake manifold vacuum is applied to the crankcase via the PCV valve, drawing fresh air into the crankcase via the breather. The airflow through the crankcase and engine interior sweeps away combustion byproduct gases, including a large amount of water vapour and incompletely burned organic compounds. This mixture of air and crankcase gases then exits, often via another simple baffle, screen, or mesh to
