THE CHEMISTRY OF MILK | Dairy Processing Handbook
Milk fat. Milk and cream are examples of fat-in-water (or oil-in-water) emulsions. The milk fat exists as small globules or droplets dispersed in the milk serum, Figure 2.15. Their diameters range from 0.1 to 20 µm (1 µm = 0.001 mm). The average size is 3 – 4 µm and there are some 10 10 globules per ml.

The maximum wear rate is 6.62 × 10 −6 mm −3 /(N m) at 600 °C. 3. The wear mechanisms of the AlMgB 14 –TiB 2 composite vary with different test temperatures in case of load at 10 N and 0.1 m/s sliding velocity. Mild abrasive scratches play an important role at 25 °C. Adhesive wear is responsible for the wear of AT73 at 300 and 600 °C.

The EGR rate is defined as the percentage of exhaust gases from the total gas mass induced into the engine. For example, an EGR rate of 33 % means that a third of the gas which enters the cylinders is actually exhaust gas and 67 % is fresh air. The higher the EGR rate the lower the NOx emissions levels.

3. CALCULATION OF MACHINE RATES
3.1 Introduction. The unit cost of logging or road construction is essentially derived by dividing cost by production. In its simplest case, if you rented a tractor with operator for $60 per hour - including all fuel and other costs - and you excavated 100 cubic meters per hour, your unit cost for excavation would be $0.60 per cubic meter.
