To solve this problem we will apply the concepts related to real power in 3 phases, which is defined as the product between the phase voltage, the phase current and the power factor (Specifically given by the cosine of the phase angle). First we will find the phase voltage from the given voltage and proceed to find the current by clearing it from the previously mentioned formula. Our values are
Real power in 3 phase
Now the Phase Voltage is,
The current phase would be,
Rearranging,
Replacing,
Therefore the current per phase is 2.26kA

Explanation:
The pump is modelled after the First Law of Thermodynamics. A reversible process means that fluid does not report any positive change in entropy:
The properties of the fluid at entrance and exit are, respectively:
Inlet (Saturated Liquid)
Outlet (Subcooled Liquid)
The power input to the pump is computed hereafter:
