(Q1) Does the mass of an object affect power requirements?
An object's energy is proportional to mass (m*g*h, 1/2*m*v**2), so the greater the mass, the more energy it takes to reach a specified height or velocity. Since Power is just energy per time, to achieve a specified height or velocity in a given time increases proportionally to mass.
(Q2) Does the mass flow rate of an engineering processes affect power input/output?
Most power cycles or power output devices rely on intensive properties (like enthalpy) with units of kJ/kg. Multiply these values by mass flow rate (mdot, or mass/time) and you get power. So, the more mass (mdot) the more power.
If neither of these guesses hits the mark, update your question.

mass of what?
power of what?
this is too generalized for an answer, sorry.
