Lubricants

Lubricant can be expressed as the substance that is applied among surfaces to control the wear and tear and improve performance. Lubricants play an essential part in the safety of machinery components like gears, shaft, linkage, cam, clutches, and many others. The quantities which affect the amount of lubricant are temperature, surrounding conditions, speed of the components, and many more.

Nutrient media is flowing at a rate of 1.5 L min in a tube that is 5 mm in diameter. The walls of the tube are covered with antibody-producing cells, and these cells are anchored to the tube wall by their interaction with a special coating material that was applied to the surface of the tube. If one of these cells has a surface area of 500 um², what is the amount of force that each cell must resist as a result of the flow of this fluid in the tube? Assume the viscosity of the nutrient media is 1.2 cP=0.0012 Pa sec.
In a paint manufacturing process, two different colored paints are being mixed in an infinitelylarge drum.Paint A, with a concentration of 30% pigment, is pumped into the drum at a rate of 10 liters perminute.Paint B, with a concentration of 17% pigment, is pumped into the drum at a rate of 17 liters perminute.Both paints have the same density of 1.0 kg/liter.If the mixture is cotinuously stirred and drained from the drum at a rate of 22 liters perminute, what isthe concentration of pigment in the resulting mixture?
A plastics plant manufactures larges pieces of plastic by continuously extruding thin sheets.As the sheets flow out of the extruder, they are cooled via forced convection and radiation.The plastic sheets are 1 mm thick, 1 m wide, and leave the extruder at a rate of 9 m/min.A fan blows air over the top and bottom surface of the sheet during the first meter after thesheet leaves the extruder. The fan accelerates the air to 3 m/s and the air is known to be at27°C at the fan outlet. At the exit of the extruder, the plastic is at 90°C. The plastic isestimated to have an emissivity of ? = 0.9 and the general surroundings are at 20°C. A) Determine the rate of heat transfer via convection and radiation from the 1-m-longsection of the plastic sheet that is being force cooled. take the surface temperature to be 90°C overthe entire section of interest.
