The symbol, kV.A (not 'kva'), represents kilovolt ampere. A volt ampere (V.A) is the unit of measurement for apparent power, which is the vector sum of true power (in watts) and reactive power (in reactive volt amperes)
"kW" (kilowatt) is a measure of rate of actual energy flow. "kVA" is AC voltage multiplied by current. Purely reactive loads (inductors and capacitors) do not dissipate power (energy) so there is no "kW" value. On the other hand, they do conduct current and a "kva" value can be worked out.
For a purely resistive load (like a bar heater, electric stove or incandescent light) "kW" and "kVA" will be the same value. For inductive loads like electric motors, the "kVA" value will be higher than the "kW" value.
Alternative AnswerWhen an AC current flows through a purely resistivecircuits, its temperature increases above the ambient temperature, and energy is lost to the surroundings through heat transfer. This energy transfer is irreversible. The rate at which this energy loss is taking place is called the true power of the circuit, and is expressed in watts (symbol: W).
When an AC current flows through a purely reactive (i.e. inductive or capacitive) circuit, during the first quarter-cycle, energy is stored in the magnetic or electric field, and returned to the circuit during the next quarter cycle. So, although energy transfer is taking place, there is no net loss of energy. The rate at which this energy transfer is taking place is called the reactive power of the circuit, and is expressed in reactive volt amperes (symbol: var).
However, most practical circuits are inductive-reactivecircuits. So, when AC current flows through an inductive-reactive circuit, some energy is permanently lost while some energy is transferred from and back to the circuit. In other words, most circuits exhibit a combination of true power andreactive power. The vector sum of true power and reactive power is called apparent power, and is expressed in volt amperes (symbol: V.A).
To summarise: (Apparent Power)2 = (True Power)2 + (Reactive Power)2
From the above equation, in a purely resistive circuit, the apparent power will be equal to the true power. For resistive-reactive circuits, the apparent power will always be larger than the true power.
The term KVA represents Kilo Volt Amps. KVA is 1000 volt amps. The product of volts times amps is another electrical term called apparent power.
The full form of KVA is kilovolt-ampere, a unit of electrical power equivalent to one thousand volt-amperes. It is commonly used to measure the apparent power in an electrical circuit.

The answer: 17070 BTU The math: 3414 BTU = 1 KVA (KW) so 5 KVA = 17070 BTU
The full form of kph is kilometers per hour. It is a unit used to measure speed or velocity.
The full form of mm Hg is millimeters of mercury. It is a unit of pressure commonly used in medicine to measure blood pressure.
It depends on the rated voltage. Take 1600 KVA and divide by KV, and you will get A.

The Perkins 100 KVA generator uses approximately 23.8 Liters per hour. The Perkins KVA generator can be purchased at any Perkins licensed dealer.

kva and kw are related as KVA = (KW/PF) pf:power factor
kva means 1000 x voltage x currentSo in order to determine the current we need to know the voltage.AnswerA kilovolt ampere (kV.A, not kva) is a measure of a circuit's apparent power, whereas the ampere(not amp) is a measure of current. These are two completely separate quantities, so your question is quite meaningless. You might have well have asked, "How metres are there in a kilogram of sugar?"
