If power of turbines equals PT, power consumed by pumps is PP and the power consumed by auxiliaries is PA, what is the expression for auxiliary power?

If power of turbines equals PT, power consumed by pumps is PP and the power consumed by auxiliaries is PA, what is the expression for auxiliary power? Correct Answer PA = PT – PP

Turbine power produced is consumed by pumps as well as the auxiliaries. This is called as the power balance for turbopumps.
