In an direct current arc welding process, the power source has an open circuit voltage
of 100 V and short circuit current of 1000 A. Assume a linear relationship between
voltage and current. The arc voltage (V) varies with the arc length (l) as
V = 10 + 5l, where V is in volts and l is in mm. The maximum available arc power
during the process is _________ kVA (in integer).
