This paper describes experimental measurements and estimation methods for density, dynamic viscosity, thermal conductivity and heat capacity of vegetable oils for this particular range of temperature Just like sunflower oil, it is considered a semidrying oil and has a variety of industrial uses. The density of the oils varies with each type and temperature. The range is from 0.91 to 0.93 g/cm 3 between the temperatures of 15 °C and 25 °C. Comparing to water, whose density is 1.00 g/ml, cooking oil is less dense are easy to use and the estimated density and dynamics viscosity values of vegetable oils at different temperatures agree well with the literature values. The average absolute deviation of density and dynamic viscosity of vegetable oils at 283.15-413.15 K are 0.23 and 7.57 %, respectively

High viscosity of vegetable oil (28 to 40 mm 2 /s), 10 to 20 times greater than petroleum diesel, is a major problem associated with the direct use of vegetable oils as fuels in CIEs. Low volatility and high viscosity of vegetable oils impede complete combustion and lead to the formation of deposits in the fuel injectors of diesel engines Experimental study of electrical properties of mineral and vegetable transformer oils 173 chemistry of the vegetable oils and high oleic vegetable oils are observed to have reasonably good oxidation behaviors [5]. During operation, the insulation of a power transformer is permanently subjected to electrical, thermal and environmental stresses Because of the renewable nature, emission advantage, and easy adaptation, vegetable-oil-based fuels are emerging as the most promising alternatives to fossil diesel for use in compression-ignition engines. In this study, a unified approach is proposed for predicting the densities of straight and processed vegetable oils from their fatty acid composition, obviating the need of measured values.

Rodenbush predicted viscosity of veg-etable oils from density data[2]. The variation of veg-etable oils quality as a result of thermal treatment was evaluated by. increasing proportions of vegetable oil blended into the fuel.3 Viscosity (the measure of a fuel's resistance to flow) is another impor-tant consideration related to the use of SVO.

The superiority of the watermelon seed oil in terms of viscosity index (VI) over the mineral oil SAE10W30 is an indication that the vegetable oil shows serious resistance to decline in viscosity with temperature than the mineral oil (Bhaumik & Pathak, 2016).

The list of vegetable oils includes all vegetable oils that are extracted from plants by placing the relevant part of the plant under pressure, to squeeze the oil out. Although few plants are entirely without oil, the oil from a small set of major oil crops complemented by a few dozen minor oil crops has become widely used and traded The density of vegetable oils ranges from 900 to 980 kg per cu m; the refractive index, from 1.44 to 1.48. the thickness of the material to be compressed, the viscosity and density of the oil, and the duration of the operation. The extraction of vegetable oils is performed in a special apparatus called an extractor, with the aid of organic. At room temperature viscosity of water is 1 mPa.Sec and for vegetable oil is 57 mPa.Sec. The above values are dynamics viscosity values. The kinematic viscosity value can be found by dividing dynamic viscosity by density of each fluid. Thus, Kinematic Viscosity = Dynamic Viscosity/Density Canola Oil: Biodiesel: Density kgL-1 @ 15.5 deg C: 0.84: 0.92: 0.88: Calorific value MJL-1: 38.3: 36.9: 33-40: Viscosity mm 2 s-1 @ 20 deg C: 4-5: 70 : 4-6: Viscosity mm 2 s-1 @ 40 deg C: 4-5: 37 : 4-6: Viscosity mm 2 s-1 @ 70 deg C-10 -Cetane number: 45: 40-50: 45-65: From Waste Vegetable Oil as a Diesel Replacement Fuel by Phillip Calais. With high viscosity, surface tension and density of vegetable oil fuels, the degree of atomization will certainly decrease, leading a longer ignition delay time. Hence, it is necessary to heat vegetable oils up to the most suitable temperature in order to reduce high viscosity, surface tension and density and meet the requirements of fuel used i

Viscosity depends on the size and shape of the particles that make the liquid, as well as the attraction between the particles. Liquids that have a LOW viscosity flow quickly (ie. water, rubbing alcohol, and vegetable oil). Liquids that have a HIGH viscosity flow slowly (ie. honey, corn syrup, and molasses) On the other hand, vegetable oils offer excellent lubricity, intrinsic high viscosity index, and good anti-wear and extreme-pressure properties. Well-formulated, biodegradable hydraulic fluids based on vegetable oils can easily pass the demanding Vickers 35VQ25 or Denison T5D-42 vane-pump wear tests

The viscosity grade of a lube oil is determined by the Society of Automotive Engineers (SAE). Oils can be separated into multigrade oils and monograde oils. Multigrade oils must fulfill two viscosity specifications, their viscosity grade consists of two numbers, e.g. 10W-40: 10W refers to the low-temperature viscosity (Winter), 40 refers to. At the HDPE to waste vegetable oil ratio of 1:1, the maximum proportion (97.85wt.%) of alkanes was obtained. Moreover, the properties of hydrocarbon fuel were superior to biodiesel and 0# diesel due to higher calorific value, better low-temperature low fluidity, and lower density and viscosity The main difference between them is the high viscosity of the vegetable oils. Nevertheless, it decreases when heating it at 70-80 [degrees]C [5], where it had a comparable viscosity to the mineral oil. We can also notice, from the curve, that the Rapeseed oil has a viscosity lower than 4,5 [mm.sup.2]/s at the highest temperature The viscosity of fuels affects their ignition temperature, heat of combustion, the rate at which they burn, density, melting points, energy density and lubricity. Vegetable oils are appealing alternatives to petrol due to their greater density, safety and lower exhaust emissions. However, the viscosity of vegetable oils also affects the ease. vegetable oil-based fuel in an unmodified diesel fuel system, the vegetable oil itself must be modified to acquire a viscosity very close to that of petroleum diesel.

If too high, the oil can't pass the fuel circuit Vegetable oils and fats as alternative engine fuels are all extremely viscous with viscosities ranging from 10 to 17 times greater than petroleum diesel fuel. Biodiesel is produced by transesterifying the parent oil or fat to achieve a viscosity close to that of diesel. The chemical conversion of the oil to its corresponding fatty ester. This work has improved the viscosity of two base oils, 150N and 500N, by blending them in different properties with four additives formulations, 5748, 801, 264, 261. All the four additives improved both base oil to very high viscosity index since viscosity index values higher than 110 were achieve Viscosity of a hydraulic fluid depends on its composition and the temperature. Low viscosity limit is determined by the lubrication properties of the oil and its resistance to cavitation. Upper viscosity value is limited by the ability of the oil to be pumped. Common viscosity of hydraulic oils is in the range 16 - 100 centistokes of used vegetable oils as well as pH, viscosity and density values. The kinds and amounts of fatty acids in oils were measured by gas chromatography.

Relative density, flash point, smoke point, crackle test, cold test and viscosity were determined for each sample. Also, the saponification, acids, ester and iodine values, as well as the fatty acid profile for each sample were investigated oil crisis of 1970s 3,4.

Vegetable oil is any oil obtained from plants and used in food products and industrially. Vegetable oil is an ester of glycerin and has fluctuating blends of fatty acids. Vegetable oil is often times used for cooking but is also used for industrial, medical, and fuel purposes. Although vegetable oil can be made from various plants, soybean oil.
