Advantages and disadvantages of the plain bearing

Advantages
Plain bearing are cheap to produce and have noiseless operation. They can be easily machined, occupy small radial space and have vibration damping properties. Also they can cope with tapped foreign matter.

Disadvantages
They require large supply of lubricating oil, they are suitable only for relative low temperature and speed; and starting resistance is much greater than running resistance due to slow build up of lubricant film
around the bearing surface.

How to find out length of holding tube in pasteurizer?

Pasteurization requires that the milk is in custody for a specified time. The appropriate length for the holding tube can be calculated by the flow rate (Q) of milk and the diameter (D) of the holding tube using the formula: Length of holding tube, L = Q x holding time/A x Î· A = Area = pi/4 x sqr D Where an efficiency factor, η, of 0.85 is used in the model.

Specific power consumption of Air compressor

Specific Power Consumption   Specific power consumption is the ratio of the power consumed by an engine to a certain force such as the amount of output the engine (equipment) produces. It allows engines (equipments) of all different sizes to be compared to see which is the most power efficient. It allows manufacturers to see which engine (equipment) will use the least power while still producing a high amount of output. Specific power consumption of Air compressor The ratio of power consumption (in KW) to the volume delivered at ambient conditions. Specific power consumption= Actual power consumed by the compressor/Measured free air delivery If the measured flow is 250 m3/hr and actual power consumption is 30KW. Then Specific power requirement = 20 KW/250 m3/hr
