"constant humidity" is a grammatically correct phrase and can be used in written English.
It refers to a consistent level of moisture in the air. It can be used in various contexts, such as describing a weather condition or discussing the ideal environment for certain plants or materials. Example: The desert region experiences constant humidity levels of around 20%, making it difficult for plants to thrive.
The constant humidity might have resulted from the long-ago failure of the first-century drainage system.
For the protection of the workers, all catwalks and access tunnels were shielded with a pliable steel mesh, which the constant humidity was quickly turning to rust.
Yet at Cragside, as with all of the trust's 300-plus historic house museums, employees still use a standard British mid-20th-century conservation method — chiefly an electric or hot water heating system that maintains constant humidity levels — to protect irreplaceable treasures, like its painting by J. M. W. Turner and its early Burroughes & Watts billiard table.
The beaker with distilled water served to maintain a constant humidity in the closed system.
The assumption of constant humidity ratio is applied in this paper for derivation of the analytical solution.
During this period, containers were kept uncapped in an enclosed space at approximately constant humidity and temperature conditions (Figure 1b).
On the first level, plain concrete specimens were experimented in a constant temperature and constant humidity room.
It was also shown that the analysis by assuming constant humidity transport properties resulted in a significant underestimation on the maximum interfacial stresses.
The tests were done at a constant humidity of 80%, under isothermal conditions, and a wet and carbonated N2 flux with 1% of CO2 was added.
We present a new design of hygroscopic tandem differential mobility analyser (HTDMA) capable of rapidly switching between measurement at constant humidity and the determination of humidograms.
In this paper, a finite element model is developed to predict the interface properties after long-term exposure to the cyclic temperature and the constant humidity.
