Sentence examples for gravity medium from inspiring English sources

On the basis of their API gravity, crude oils can be classified as heavy, medium, and light as follows: Heavy: 10 20° API gravity Medium: 20 25° API gravity Light: above 25° API gravity Crude oil also is categorized as "sweet" or "sour" depending on the level of sulfur, which occurs either as elemental sulfur or in compounds such as hydrogen sulfide.

It is concluded that fruit pulp supplementation enhanced the rate and yield of ethanol production in a very high gravity medium.

Saccharomyces cerevisiae was inoculated to the very high gravity medium containing 30%to40%0% w/v glucose with and without supplementation of three selected fruit pulps (mango, banana, and sapota).

The very high gravity fermentation medium composition is the same as the abovementioned MPYD medium with high glucose concentration (300 to 400 g/L); 4% fruit pulp/puree was supplemented to 300 and 400 g/L sugar medium to evaluate the potential effect of fruit pulps in enhancing the ethanol production, and the medium without supplementation of fruit pulp was treated as control.

However, the high sugar content of the very high gravity fermentation medium causes an increase in the osmotic pressure, which has a pessimistic effect on yeast cells, and the fermentations are rarely fast and complete.

Despite rumours earlier in the week that the company's Sea Lion well was producing low grade heavy oil, the company said tests on samples brought back to the UK have shown it is "medium gravity" crude oil and there is more of it than initially expected.

The operating variable was the specific gravity of the medium, feed inlet pressure and feed inlet flow rate.

The API gravities of the two crude oil samples were found to be 23° and 31°API, indicating that the oil field produces medium gravity crudes.

The testing fluids were a medium gravity crude oil, seawater concentration brine, formation equivalent brine and the carbonated version of these brines.

The results of the experimental work highlighted the successful application of the synergic combination of alkali, surfactant and CO2 gas for improving recovery of medium gravity crudes.

The filters are divided by the force that causes filtration: vacuum (i.e., a negative pressure at the filter medium), gravity alone (i.e., the hydrostatic head of the liquid above the medium), centrifugal force (i.e., an amplified gravity effect), fluid pressure (imposed by the suspension feed pump), mechanical pressure (a squeezing effect), and the use of other force fields.
