Q1/ A hydraulic oil ISO 68 is flowing by velocity 20 ft/sec through a hydraulic line at a volume flow rate of 250 GPS (g/sec). Find the pressure drop in bar unit for a hose volume of 70 m³. Note: Oil ISO 68 density is 54.9 lb/ft³ or 880 Kg/m³ and a kinematic viscosity of 68 cSt At 104°F. ( Use IS unit )

how is v1 calculated from pressure

After circulating through the engine, the oil falls back to the oil sump to cool. Select one: True O False

A cylindrical pressure vessel of radius r = 10.2 in is filled with a gas at a pressure of 455.0 psi (gauge). The top of the vessel is secured by an end cap of radius R = 22.0 in, of weight 31.0 lbf, and held in place by 14 bolts. Bolts (more exist than sh End cap

Which factor has the greatest impact on flow? a. viscosity b. radius of the vessel c. pressure gradient d. length of the vessel

An organic oil was produced from the plant materials and animal fats. Tests showed that the oil behaved differently in cold weather as compared to its performance in hot condition and as such it was graded as SAE 15W-40. Based on its rheological behavior, what kind of fluid is the oil produced? A. NEWTONIAN B. NON-NEWTONIAN C. IDEAL FLUID
