Web28 Mar 2024 · The thickest motor oil readily available on the market is 40W70. This oil is made for antique cars with diesel engines that burn oil excessively. The thickness of oil is more commonly referred to as viscosity grade. The higher the number, the more resistance the oil exhibits. Due to the addition of modern polymers, multi-weight oils are common. WebIn the metric system, the unit of kinematic viscosity is the square centimeter per second or the stoke. The centistoke (one hundredth of a stoke) is more generally used. The kinematic viscosity of a liquid can be looked upon as …

WebFor D = 160 mm the minimum acceptable oil film thickness is The minimum film thickness using a safety factor of Cs = 2 applied to the load, and assuming an “extreme case” of c = 0.22 mm, is calculated as follows: The Sommerfeld number is From Fig. 5.9, using S = 0.01625, we find h0 /c = 0.06, and the minimum film thickness h0 is 0.0132 mm. WebGearboxes do not have an oil pump, so the high viscosity is needed to distribute the oil and to keep it on the metal surfaces, as only the lowermost part of the gears is located in the oil sump. Depending on the type, these … refund on airline ticket
