The phrase "assumed quantity" is correct and usable in written English.
It can be used in contexts where a quantity is taken for granted or accepted without verification, often in mathematical or scientific discussions.
Example: "In our calculations, we used an assumed quantity of 50 liters for the fluid volume."
Alternatives: "estimated amount" or "presumed value".
To reduce the amount of information to be exchanged, we assume the quantity γ ̂ k [ n ] to be quantized on a logarithmic scale using a uniform B-bit quantizer.
This factor predicts the retinal ganglion cell density, assuming this quantity is M-scaled [20].
This move becomes evident in certain physical questions, e.g., in the study of condensation and rarefaction, where Albert openly disagrees with Buridan by arguing that condensation and rarefaction are possible only through the local motion of the parts of a body, and without needing to assume some quantity that would have a distinct reality on its own.
Comparisons of effect sizes for the same type of intervention, under different conditions of study design and conduct quality, would then be possible (assuming sufficient quantity and variety of original studies in the SRs).
In this work it is assumed that the quantity of anthropogenic greenhouse gases emitted to the Earth's atmosphere is proportional to the quantity of heat rejected to the environment by internal combustion heat engines.
The char particle emissivity was either treated as a quantity independent of the wavelength (i.e., assuming gray-body behavior), or as a quantity assumed to depend linearly on the wavelength and using pertinent published emissivity data.
It is assumed that The quantity f retarding the movement of the particle is due to friction caused by the surrounding medium.
where k is some positive quantity assumed to have mean one and variance θ.
It is assumed that this quantity does not depend on the choice of the collection.
We further assumed that the quantity of different mental images as well an imbalance between positive and negative mental images would be connected to depression severity.
