The phrase "and hence the quantity of" is correct and usable in written English.
It can be used to indicate a conclusion or result that follows logically from a previous statement, particularly in scientific or analytical contexts.
Example: "The increase in temperature affects the reaction rate, and hence the quantity of product formed will also rise."
Alternatives: "therefore the amount of" or "thus the level of".
Banks are just another kind of financial intermediary, and the size of the banking sector — and hence the quantity of outside money — is determined by the same kinds of considerations that determine the size of, say, the mutual fund industry.
High infiltration can reflect high recharge, therefore decreasing the potential of surface runoff and hence the quantity of transported materials.
Malt extract (ME) is probably the single most important parameter for maltsters and brewers due to its influence on ethanol production and hence the quantity of beer produced.
As the loading is increased beyond 5 wt %, it is clear that the Sn−Sn interactions, and hence the quantity of extraframework Sn x O y species, increases, evidenced by increased Sn−Sn coordination numbers, an increase in the coordination number of the longer Sn−O distance, and an increase in the splitting structure shown in the χ data.
Scale-up of the reactor was investigated by increasing the gap-width of the annulus and hence increasing the quantity of feed processed.
Hence the quantity of bait present in a drumline installation is not large.
Hence the quantity of transmission of message is reduced.
Hence, the quantity of interest of this model is defined on both a parametric space and a stochastic space.
Hence, the quantity of MnO2 required in the electrode layer has thereby been reduced significantly in favor of achieving higher specific capacitances.
Realistic model of roughness requires inclusion of randomness in surface morphology, hence the quantity of interest, the mean admittance is obtained (by taking ensemble average over all possible random configurations).
From the quantity of brackish water inside the solar stills, it is shown that due to large amount of brackish water inside the conventional solar still, it requires highest time for evaporation as well as condensation; hence, the quantity of distillate output produced from conventional solar still is least and highest for solar still having aluminum plate.
