Q=CMT
Where C=4.2*1000
1. 1 kilowatt hour = 3600000 joules, so 10KW = 36000000
joules
2. T=50-15=35
3. 36000000=4200*M*35
M=245kg
Answer: Theoretically. , it can burn 245 kilograms of water per hour.
A ten kilowatt generator should be equipped with a 4.2 kvar capacitor
A 10 kilowatt generator should be equipped with a compensation capacitor. with a capacity of 4.2kvar. The natural power factor before compensation is approximately =0.8. When the power factor is increased to 0.95 through capacitor compensation, according to the table in "New Electrician's Common Calculation Manual", it turns out that the compensation capacity required for each 1 kW of power is 0.42 kvar, therefore the capacity of the compensation capacitor which must be configured for a 10Kw motor = 10*0.42= 4.2kvar.
