VISCOSITY. The specified maximum Viscosity for Fuel Oils provided under this contract shall be as specified in Table I and Table II, elsewhere within this specification. Delivered product having a viscosity greater than that specified for the respective product shall be adjusted in price as specified elsewhere herein for NON-COMPLYING PRODUCT. Delivered product having a viscosity greater than the specified shall be removed from the purchasing agency’s tank and replaced with product conforming to specifications, at purchasing agency’s discretion based on excessive filter maintenance and/or poor burner performance. The Viscosity shall be determined using - ASTM Test Method D445-12 (IP #71-84), latest revision thereof, or approved equivalent method, and ASTM D2161-10, conversion of Kinematic Viscosity to Saybolt Universal Seconds (SUS) or to Saybolt Furol Seconds (SFS), latest revision thereof, or approved equivalent method, - relative to the individual characteristics of the product being tested. After receiving a written request by purchasing agency, the contractor’s delivery ticket will state the fuel’s viscosity (cSt, SUS, SFS).
VISCOSITY. The specified maximum Viscosity for Fuel Oils provided under this contract shall be: thirty three (33 SUS @100°F) Saybolt Universal Seconds at one hundred degrees Fahrenheit, maximum, for 1-D fuel oil; and thirty eight (38 SUS @100°F) Saybolt Universal Seconds at one hundred degrees Fahrenheit, maximum, for 2-D and 2-PD fuel oils. Delivered product having a viscosity greater than 33 SUS @ 100°F or 38 SUS @ 100°F, respectively, shall be adjusted in price as stated elsewhere herein for NON-COMPLYING PRODUCT. Delivered product having a viscosity greater than 35 SUS @ 100°F for 1-D; or 40 SUS @ 100°F for 2-D or 2-PD shall be removed from the purchasing agency’s tank and replaced with product conforming to specifications, at purchasing agency’s discretion based on excessive filter maintenance and/or poor vehicle performance. The viscosity shall be determined using ASTM Test Method D445-12 (IP #71/84), or latest revision thereof; and ASTM D2161-10, 1999e2, conversion of Kinematic Viscosity to Saybolt Universal Seconds (Table 1), or latest revision thereof relative to the individual characteristics of the product being tested.
VISCOSITY. The specified maximum Viscosity for Fuel Oils provided under this contract shall be thirty eight (38 SUS @100°F) Saybolt Universal Seconds. Delivered product having a viscosity greater than 38 SUS @ 100°F, respectively, shall be adjusted in price as detailed in the NON-COMPLYING PRODUCT & OPERABILITY TABLE FOR PRICE DEDUCTIONS. Delivered product having a viscosity greater than 40 SUS @ 100°F shall be removed from the purchasing agency’s tank and replaced with product conforming to specifications, at purchasing agency’s discretion based on excessive filter maintenance and/or poor vehicle performance.
VISCOSITY. Produce slurry with a viscosity within the range of 30 to 45 seconds per quart (32 to 48 seconds/liter), as measured by the Xxxxx Cone Method.
VISCOSITY. The viscosity of fuel is a measure of its resistance to flow. It is important in the fuel auxiliary equipment since it determines pumping temperature, atomizing temperature and oil pump pressure. In order to obtain proper operation of the gas turbine, the maximum viscosity at the fuel nozzles must not exceed 10 centistokes for pressure atomizing or low-pressure air-atomization fuel systems, and 20 centistokes for high-pressure air-atomizing systems. When these limits are exceeded, poor ignition characteristics, smoking, unsatisfactory combustor exit temperature distribution, lowered combustion efficiency or formation of carbon may occur. In most cases, fuel heating must be employed to insure that these viscosity limits at the fuel nozzle are met under all ambient conditions. In all cases the fuel at initial light-off must be at or below 10 cSt viscosity. Minimum viscosity limits are imposed to safeguard the high pressure fuel pump, which depends on the lubricating qualities of the fuel for satisfactory operation. It should be noted that naphtha fuel can have a minimum viscosity as low as 0.5 cSt at 100(Degree)F (37.8 (Degree)C). Special pumps may be required for viscosities below 1.8 cSt at 100(Degree) F.
VISCOSITY. Viscosities at two temperatures are needed for a viscosity-temperature relationship for the fuel; the two temperatures normally being 100(Degree)F (37.9(Degree)C) and 210(Degree)F (98.9(Degree)C). If the pour point is between 70(Degree)F (21(Degree)C) and 90(Degree)F (32(Degree)C), the lower temperature should be 122(Degree)F (50.0(Degree)C). For pour points between 90(Degree)F (32(Degree)C) and 120(Degree)F (49(Degree)C), the lower temperature should be 150(Degree)F (65.6(Degree)C).
VISCOSITY. The viscosity shall be expressed as Kinematic vis. cSt at 210 DEG. F. by ASTM D 445. It shall not be less than 4.2; nor more than 10.2. oils of higher viscosity may be used, provided the penetration requirements are met. The purchaser may specify the viscosity best suited to his requirements, allowing the supplier a tolerance of plus or minus 10 percent of the value specified (Equivalent vis. SUS at 210 DEG. F. shall be 40 min. to 60 max. by ASTM D 88).
VISCOSITY. Each load of blended asphalt-rubber shall be tested by the supplier using a Xxxxx type field viscometer. The viscosity of the final product shall be in the range of 1,500 to 5,000 centipoise.
VISCOSITY. Liquid phase viscosities are modeled in terms of pure component viscosities and the phase concentrations of the organic, water and surfactant: ℓ 1ℓ w 2 ℓ o 3ℓ 3 μ = C μ eα1(C2ℓ+ C3ℓ) + C μ eα2(C1ℓ + C3ℓ) + C α e(α4C1ℓ + α5C2ℓ ) for ℓ = 1, 2, or 3 (2.77) where the α parameters are determined by matching laboratory microemulsion viscosities at several compositions. In the absence of surfactant and polymer, water and oil phase viscosities reduce to pure water and oil viscosities (μw, μo). When polymer is present, μw is replaced by μp defined below. The following exponential relationship is used to compute viscosities as a function of temperature (T).
