The lactic acid bacteria convert the sugar in milk (lactose) to lactic acid. The rennet contains enzymes that modify proteins in milk. Specifically, rennet contains rennin, an enzyme that converts a common protein in milk called caseinogen into casein, which does not dissolve in water.
KVA is a unit of power. From ohms law it can be shown that in any circuit, the power of any element in the circuit is the product of the voltage and current (V x I) . Hence KVA is 1 Kilovolt times an Ampere and hence 1000 volts times an ampere. A unit of apparent power, equal to 1,000 volt-amperes; the mathematical product of the volts and amperes in an electrical circuit. A term used to describe the product of currend and voltage, expressed in kilovolt ampereres (KVA). KVA is the unit of transformer rating.
Kva and watts are different term that represents the same thing but for different uses. When we use the term kva we are basically talking about potential power, as appose to watts that is referred to as actual power. Kva = volts x amps / 1000 and Kw which represents watts is volts x amps x power factor / 1000. So a 5 kva generator is equivalent to about 5000 watts. I was searching on the Internet one day for a type of calculator to calculator kva into watts. Here is the link to a website that has a build in calculator to assist in calculating kva to watts.
