Batching, Mixing, Placing and Compaction of Concrete

Batching is the process of measuring concrete mix ingredients either by volume or by mass and introducing them into the mixture. Traditionally batching is done by volume but most specifications require that batching be done by mass rather than volume. Percentage of accuracy for measurement of concrete materials as follows. Cement:

Power Substation Design Calculations - A Checklist of 18

Jun 17, 2020 · Figure 15: Voltage drop study. Substations are vast. A piece of wire connecting a battery to a motor load can span hundreds of feet. Because the copper or aluminum wire has resistance, some power is lost as heat resulting in a voltage drop along the wire. Due to this drop, the voltage at the receiving end may not be adequate to start the motor.

Plant Engineering | Three steps to size motors

Aug 06, 2019 · A motor may lose the capability to cool itself if turned down too far. For motors that will use a variable frequency drive, ensure that the motor selected is a 3-phase inverter-duty-rated motor. Duty cycle of the load defines how much time the motor must run and stop. The motor’s rated duty cycle must be better than that required by the load.
