The formula is: (Average grams gained/day X % survival rate )/Feed Conversion X 10 So with an average growth of 61 g (for instance an end weight of 2,257 kg in 37 days) and a survival rate of 96% (100 4% mortality) and a feed conversion of 1.62, the outcome would be:

What is storage factor in total RAID capacity formula

RAID 0: Striping with no redundancy at all. All raw disk space of the devices that make up the array is usable for storage, thus the efficiency factor = 1. Can be used with any number of disks but can not survive the failure of any disks in the array. RAID 1: Mirroring but no striping.

Determining Electric Motor Load and Efficiency

Overloaded motors can overheat and lose efficiency. Many motors are designed with a service factor that allows occasional overloading. Service factor is a multiplier that indicates how much a motor can be overloaded under ideal ambient conditions. For example, a 10-hp motor with a 1.15 service factor can handle an 11.5-hp load
