- An oil is being pumped inside a 10.0 mm diameter pipe. The oil’s density is 855 kg/m3 and its viscosity is 2.1×10-2Pa·s. It is required that the flow remain in the laminar regime and thus the Reynolds number cannot exceed 2100.What is the maximum velocity in the pipe?A 100 mm long and 60 mm diameter journal bearing supports a load of 2500 N at 600 r.p.m. If the room temperature is 20°C, what should be the viscosity of oil to limit the bearing surface temperature to 60°C?
